Christians pray for the repentance of human beings they present themselves as 'enemies' {Mtt.5:43-48}
according to Jesus Christ teachings.
Christians have the ability of Jesus Christ to cast 'evil-spirits'{devil and evil-spirits} in men{wicked/possessed} or environments out to designated areas {deserts} as the angels of God bounds them in chains {Tobit 8:3} until Jesus Christ comes again to cast them into the Pit of abyss.
suffer not the witch to live; a witch is an evil-spirit not a human being so you cast the demon out of a living human being to where they belong in order to help that human being to regain as well as enjoy the liberation that JESUS CHRIST gives to human beings thus "for this was the Son of Man made manifest to destroy the works of darkness" {1 John 3:8}
JESUS CHRIST came on earth to set mankind free from the bondage of Sin and the devil, he did not come to kill human beings rather set us free and destroy the works of devil, wickedness, death, sin, evil, un-forgiveness e.t.c from our lives thus "The thief comes only in order to steal and kill and destroy. I came that they may have and enjoy life, and have it in abundance [to the full, till it overflows]." {John 10:10}
The Name JESUS means "He will deliver his brothers and sisters from Sin and bondage of the devil" {Matthew 1:21}
Those who believe in Jesus Christ also carry his Spirit to deliver others from sin, consequences of sin and the bondage placed on men by the devil thus Christians are Christ-like through consistent knowledge of His Word written in the Holy Bible.
Anyone who refuses to repent from his/her sins as well as surrender to Jesus Christ as Lord and Savior of his/her life has already chosen death {untimely death/eternal damnation} by default. Anyone who tries to harm us as we follow Christ Jesus will definitely be hit by the God we serve who is a consuming fire and a jealous God {Deut.4:24} for we are the flame of his Fire {Hebrews 1:7} hence it is a serious risk for that person {'if you do not repent, you will perish likewise' Luke 13:3}. Since this decision most times are made because of Ignorance, those who have come to the knowledge of this RISKY DECISION should take part in praying for sinners/unbelievers as well as sharing the Good-News of Jesus Christ to every human being in order to allow the Holy Spirit to lead souls to repentance and genuine Conversion of Sinners.
We are therefore invited to regular meditation on the Word of God written in the Holy Bible and Consistent Evangelization to the whole world under the leading of the Holy Spirit.
May the Holy Spirit grow us in his Grace and Faith in Jesus Name. Amen.
