Each of us(human being) should always get ready for our biological death(with or without any sign/sickness) or the second coming of Jesus Christ Crucified; Our Lord:

"O death, where is your victory? O death, where is your sting?

56 Now sin is the sting of death, and sin exercises its power [upon the soul] through [the abuse of] the Law.

57 But thanks be to God, Who gives us the victory [making us conquerors] through our Lord Jesus Christ.

58 Therefore, my beloved brethren, be firm (steadfast), immovable, always abounding in the work of the Lord [always being superior, excelling, doing more than enough in the service of the Lord], knowing and being continually aware that your labor in the Lord is not futile [it is never wasted or to no purpose]." (1 Cor. 15:55-58 ampc)


Death is not a bad thing rather an aspect of human lifestyle, death is part of human experience though not all human being will die or experience biological death before Jesus second coming thus

"Take notice! I tell you a mystery (a secret truth, an event decreed by the hidden purpose or counsel of God). We shall not all fall asleep [in death], but we shall all be changed (transformed)

52 In a moment, in the twinkling of an eye, at the [sound of the] last trumpet call. For a trumpet will sound, and the dead [in Christ] will be raised imperishable (free and immune from decay), and we shall be changed (transformed)." (1 Cor. 15:51-52 ampc)


If someone is sick around you, pray for him or her FIRST to repent and receive salvation inside Jesus Christ Crucified which may or may not lead to physical biological death or healing. If biological death occurs, you thank God that he/she has gone to be with Christ Jesus in Heaven. If he/she receives physical healing, we thank God also while we continue to live with the consciousness of biological death with or without signs of sickness OR the sudden appearance of Jesus Christ Crucified in the sky to call(rapture) His elect(those who will still be living their lives by faith in Jesus death on the Cross and His resurrection) as at the time of His sudden appearance.


The death of a believer should not be accompanied with sorrow or depression or hopelessness or loss-of-faith or getting angry with GOD rather with *thanksgiving* because He alone created human lives and He has the right/choice to take back our lives at any given time with or without signs because He has revealed this truth in His written word contained in the holy bible
thus
"Now also we would not have you ignorant, brethren, about those who fall asleep [in death], that you may not grieve [for them] as the rest do who have no hope [beyond the grave].

14 For since we believe that Jesus died and rose again, even so God will also bring with Him through Jesus those who have fallen asleep [in death].

15 For this we declare to you by the Lord’s [own] word, that we who are alive and remain until the coming of the Lord shall in no way precede [into His presence] or have any advantage at all over those who have previously fallen asleep [in Him in death].

16 For the Lord Himself will descend from heaven with a loud cry of summons, with the shout of an archangel, and with the blast of the trumpet of God. And those who have departed this life in Christ will rise first.

17 Then we, the living ones who remain [on the earth], shall simultaneously be caught up along with [the resurrected dead] in the clouds to meet the Lord in the air; and so always (through the eternity of the eternities) we shall be with the Lord!

18 Therefore comfort and encourage one another with these words." (1 Thess. 4:13-18 ampc)

The death of other human being should help us to reflect about our own lives, place ourselves in the position of the dead person with questions like "What if I am this person lying dead here or being buried; where will I spend my eternity (Heaven or Hell-fire) ?"
then make *adequate adjustments towards a renewed faith and commitment with Jesus Christ Crucified who is THE ONLY MEANS OF SPENDING ETERNITY IN HEAVEN*
thus

"Jesus said to him, I am the Way and the Truth and the Life; no one comes to the Father except by (through) Me." (John 14:6 ampc)

"All whom My Father gives (entrusts) to Me will come to Me; and the one who comes to Me I will most certainly not cast out [I will never, no never, reject any human being who comes to Me]." (John 6:37 ampc)

"I assure you, most solemnly I tell you, he who believes in Me [who adheres to, trusts in, relies on, and has faith in Me] has (now possesses) eternal life." (John 6:47 ampc)

"I assure you, most solemnly I tell you, the person whose ears are open to My words [who listens to My message] and believes and trusts in and clings to and relies on Him Who sent Me has (possesses now) eternal life. And he does not come into judgment [does not incur sentence of judgment, will not come under condemnation], but he has already passed over out of death into life." (John 5:24 ampc)


"And just as Moses lifted up the serpent in the desert [on a pole], so must [so it is necessary that] the Son of Man be lifted up [on the cross],

15 In order that everyone who believes in Him [who cleaves to Him, trusts Him, and relies on Him] may not perish, but have eternal life and [actually] live forever!

16 For God so greatly loved and dearly prized the world that He [even] gave up His only begotten (unique) Son, so that whoever believes in (trusts in, clings to, relies on) Him shall not perish (come to destruction, be lost) but have eternal (everlasting) life.

17 For God did not send the Son into the world in order to judge (to reject, to condemn, to pass sentence on) the world, but that the world might find salvation and be made safe and sound through Him.

18 He who believes in Him [who clings to, trusts in, relies on Him] is not judged [he who trusts in Him never comes up for judgment; for him there is no rejection, no condemnation—he incurs no damnation]; but he who does not believe (cleave to, rely on, trust in Him) is judged already [he has already been convicted and has already received his sentence] because he has not believed in and trusted in the name of the only begotten Son of God. [He is condemned for refusing to let his trust rest in Christ’s name.]" (John 3:14-18 ampc)


"And he who believes in (has faith in, clings to, relies on) the Son has (now possesses) eternal life. But whoever disobeys (is unbelieving toward, refuses to trust in, disregards, is not subject to) the Son will never see (experience) life, but [instead] the wrath of God abides on him. [God’s displeasure remains on him; His indignation hangs over him continually.]" (John 3:36 ampc)


"Because if you acknowledge and confess with your lips that Jesus is Lord and in your heart believe (adhere to, trust in, and rely on the truth) that God raised Him from the dead, you will be saved." (Romans 10:9 ampc)


"Let it be known and understood by all of you, and by the whole house of Israel, that in the name and through the power and authority of Jesus Christ of Nazareth, Whom you crucified, [but] Whom God raised from the dead, in Him and by means of Him this man is standing here before you well and sound in body.

11 This [Jesus] is the Stone which was despised and rejected by you, the builders, but which has become the Head of the corner [the Cornerstone].

12 And there is salvation in and through no one else, for there is no other name under heaven given among men by and in which we must be saved." (Acts 4:10-12 ampc)


"Now when they heard this they were stung (cut) to the heart, and they said to Peter and the rest of the apostles (special messengers), Brethren, what shall we do?

38 And Peter answered them, Repent (change your views and purpose to accept the will of God in your inner selves instead of rejecting it) and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of and release from your sins; and you shall receive the gift of the Holy Spirit.

39 For the promise [of the Holy Spirit] is to and for you and your children, and to and for all that are far away, [even] to and for as many as the Lord our God invites and bids to come to Himself." (Acts. 2:37-39 ampc)


"You also must be ready therefore, for the Son of Man is coming at an hour when you do not expect Him." (Matthew 24:44 ampc)

"For this reason, because I have heard of your faith in the Lord Jesus and your love toward all the saints (the people of God),

16 I do not cease to give thanks for you, making mention of you in my prayers.

17 [For I always pray to] the God of our Lord Jesus Christ, the Father of glory, that He may grant you a spirit of wisdom and revelation [of insight into mysteries and secrets] in the [deep and intimate] knowledge of Him,

18 *By having the eyes of your heart flooded with light, so that you can know and understand the hope to which He has called you, and how rich is His glorious inheritance in the saints (His set-apart ones)*,

19 And [so that you can know and understand] what is the immeasurable and unlimited and surpassing greatness of His power in and for us who believe, as demonstrated in the working of His mighty strength,

20 Which He exerted in Christ when He raised Him from the dead and seated Him at His [own] right hand in the heavenly [places],

21 Far above all rule and authority and power and dominion and every name that is named [above every title that can be conferred], not only in this age and in this world, but also in the age and the world which are to come." (Ephesians 1:15-21 ampc)
