WILLFUL SINNERS ARE PART OF THE KINGDOM --but not for long!
"Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach [them], the same shall be called great in the kingdom of heaven." Matthew 5:19
Yes, the least are part of the kingdom --but not for long.
"Jesus answered them, Verily, verily, I say unto you, Whosoever committeth sin is the servant of sin. And the servant abideth not in the house for ever: but the Son abideth ever." John 8:34-35
The servant of sin is least in the Kingdom and will be cast out. Here are some commentaries on this verse:
"Whosoever shall break. What an awful consideration is this! He who, by his mode of acting, speaking, or explaining the words of God, sets the holy precept aside, or explains away its force and meaning, shall be called least - shall have no place in the kingdom of Christ here, nor in the kingdom of glory above. That this is the meaning of these words is evident enough from the following verse.
The Pharisees, by dividing the law into greater and lesser precepts, made no small part of it void by their traditions and divisions,
Mat_23:23; Mat_15:3-6. Jesus says that in his kingdom all this
vain division and tradition would cease. Such divisions and
distinctions would be a small matter. He that attempted it should be
the least of all. People would be engaged in yielding obedience to
all the law of God without any such vain distinctions.
Mat 5:19 - One of the least - So accounted by men; and shall teach
-Either by word or example; shall be the least - That is, shall have
no part therein.
