The Kingdom of God is given to a people yielding its fruits.
If a person bears fruit in and for the Kingdom of God, then God, Himself, will purify that person's life enabling him to bear more fruit.
Bu if a person bears no fruit for the Kingdom of God, then God, Himself, will take away that person's portion in the Kingdom of God and it will be given to another.
Many are called by God but few are chosen.
I show you a mystery, we are purified by God after we begin to bear fruit, not before.
If we wait for God to purify us before we begin to serve Him, He never will.
But if we begin to serve God while yet being impure we will be made pure.
This is what is meant by the parable, he who is faithful in the little shall be entrusted with much.
Brethren, what prevents you from serving God.
