God is not going to reject any of His own. He said we are saved to the uttermost, and I stand on it. This teaching that God is somehow going to turn many that are truly His into outer darkness, turn them away from the Kingdom, is nothing but lies from the devil.
Paints a picture of an unloving God. One who, don't do enough works in this world, you will not be part of the Bride of Christ in the next. One that will profess to you, 'I never knew you' because you failed to do certain things.
'But, oh, they are saved,' they claim. If so, why are they denied access into God's kingdom? Does not make sense.
The truth of the matter is, ALL that the Father gives to the Son, He will keep. All true believers, the church, will enter that glorious kingdom. Those who are not of the church will spend eternity in hell because they rejected the only means of escape from those eternal flames.
No, God will not turn any true believer away from entrance into the kingdom of heaven. It is in the Word of God and one can take that to the bank as being a valid promissory note from God Himself.
