This chapter deals with the way we should live and act in the kingdom of the heavens:
1) we should become like little children (vv. 2-4);
2) we should not stumble others or set up any stumbling block (vv. 5-9);
3) we should not despise even a little believer (vv. 10-14);
4) we should hear the church and not be condemned by it (vv. 15-20);
5) we should forgive a brother without limit (vv. 21-35).
All this indicates that to enter into the kingdom of the heavens we must be humble and not despise any believer, but love our brother and forgive our brother.
