Many of those gathered at the Jordan had been present at the baptism of Jesus; but the sign then given had been manifest to but few among them. During the preceding months of the Baptist’s ministry, many had refused to heed the call to repentance. Thus they had hardened their hearts and darkened their understanding. When Heaven bore testimony to Jesus at His baptism, they perceived it not.
How often our hardness of heart stops is from seeing the power and leading of God.
