Note here, 1. The modesty of John's refusal: John forbade him, and refused to admit him. But why? 1. In regard of Christ, because he knew he needed it not: such was his majesty and greatness, that he was above it: and such was his purity and holiness, that he could not want it.
2. In respect of himself, he knew his own uncleanness: I have need to be baptized of thee, &c. He thought it unsuitable that a sinner should baptize and wash him that was no sinner.
3. With respect to the people; lest they seeing Christ baptized should apprehend him to be a sinner, and one that wanted the baptism of repentance as well as themselves.
Observe, 4. As the modesty of John's refusal, so the reason he assigns for it: I have need to be baptized of thee; as if he had said, "Thou art purity, I am pollution; thou art spirit, I am flesh; humble apprehension has this holy man of himself.
Learn, That the more holy a person is, the more sensible he is of his unholiness; where there is most grace, there is the greatest sense of the want of grace.
