Our Pride and Love of Money will NEVER ALLOW us to see God's Kingdom, and will always deceive us, if NOT checked:

Obadiah 1:3
The PRIDE of your HEART has DECEIVED you...

Mark 4:19 KJV
And the CARES of this World, and the DECEITFULNESS OF RICHES, and the LUSTS of other things entering in, CHOKE the Word, and it becometh UNFRUITFUL.

It's because of the LUST for more and more Money and Popularity with the World, is why MANY, including the Great Preachers are BLINDED spiritually, and will NOT see God nor ENTER His Kingdom, if not KILLED in them:

Matthew 5:8 KJV
Blessed are the PURE in heart: for they shall SEE God.

Preachers won't like to major on the NEW COVENANT because it's not as "lucrative" or PROFITABLE (in terms of Moneymaking) for their CHURCH BUSINESS as the old.

Moreover, "compulsory giving" like TITHING, FIRST FRUITS, etc are NOT part of the New Covenant, but "cheerful giving" (it's up to you, whether you give LITTLE or MUCH; and WHEN you give, give to the poor and needy, NOT the "RICH" ).

Therefore, it is easier to have great Teachers/Preachers of the Bible or Law, Holiness, Miracles, Healing, Prosperity, Deliverance, etc but STILL have the REALITY of the Cross of Christ (discipleship): the New Covenant, which is living by the Holy Spirit MISSING.

I really won't like to totally blame any False Teacher/Pastor/Man for leading people astray because their VICTIMS have got the Bible. And we REALLY DESERVE TO BE DECEIVED by them in that case.

Jesus clearly stated it severally that WITHOUT the New Covenant Life, NO ONE can be SAVED or ENTER God's Kingdom.

Let's have a DEEP look at these:

Matthew 5:20 KJV
For I say unto you, That EXCEPT your righteousness shall EXCEED the righteousness of the Scribes and Pharisees, ye shall in NO CASE ENTER into the kingdom of Heaven.

The "righteousness" of the Scribes and Pharisees is the standard of the OLD COVENANT, the life UNDER the Law of Moses. However, Jesus did say our lives must EXCEED all that to be SAVED.

Now, this next passage is common but NOT WELL understood by MANY, including Pastors/Preachers:

Matthew 11:12 KJV
And FROM THE DAYS of John the Baptist UNTIL NOW the kingdom of heaven suffereth VIOLENCE, and the VIOLENT take it by FORCE.

Right, it's common for people to refer to this during prayers and all, but it's actually talking about the New Covenant (God's Kingdom), as against the OLD COVENANT (the Kingdom of Earth).

Okay, let's see the verse next to it:

Matthew 11:13 KJV
For all "the prophets and the law" (means Old Testament) prophesied UNTIL John.

Additionally, MANY try to MIX THE TWO, but Jesus CONDEMNED such:

Matt.9.17 - And NO ONE puts NEW WINE into Old WINESKINS. The old skins would BURST from the pressure, spilling the wine and ruining the skins. New wine MUST be STORED in new wineskins. THAT WAY both the wine and the wineskins are PRESERVED."

It's not just about using the Bible, preaching Holiness, Repentance and all, but actually following the New Covenant life self denial and taking up the Cross:

Matthew 16:24 KJV
Then said Jesus unto his disciples, If any man will COME after me, let him DENY himself, and take up his CROSS, and FOLLOW ME.

The New Covenant is about Heavenly Prosperity, NOT Earthly Prosperity like the Old Covenant.

The Old Covenant is for BABES, while the New Covenant is for the Mature ones who know that the things of earth doesn't last forever, and are inferior to heavenly treasures.

DON'T STORE UP:
Matt.6.19 - "Don't store up TREASURES here on earth, where they can be eaten by moths and get rusty, and where THIEVES break in and STEAL.

STORE UP:
Matt.6.20 - Store your TREASURES in Heaven, where they will NEVER become moth-eaten or rusty and where they will be SAFE from thieves.

AND SEEK FIRST:

Matthew 6:33 KJV
But SEEK YE FIRST the kingdom of God, and his RIGHTEOUSNESS; and ALL these things shall be ADDED unto you.

I think we should rather "believe and commit" to Jesus (the way, the TRUTH, and the Life): NOT ANY Religious Man.

Matthew 6:21 KJV
For where your TREASURE is, there will YOUR HEART BE also.

May Jesus Bless You.
