What we might not understand at first, however, is why Jesus wanted to be baptized. He had no sins that needed to be washed away. He had nothing to be repentant about. John picked up on that right away: “I need to be baptized by you, and do you come to me?” Jesus answered, “Let it be so now.” He did it for us - for each of us! No, he didn’t have to be baptized for the forgiveness of his sins. But he was baptized anyway. He stood in line with the others who were there. He wanted the world to know that he was willingly standing with sinners, in the place of sinners.
First and foremost, the object of our faith is Jesus. We know and believe in Jesus and what he has done for us. And along with that trust, comes trust in all other promises that he has made in his Word. It’s not our faith that is strong. It is the object of our faith that is strong, and he is the One who saves! Maybe “strong” or “weak” aren’t the best descriptors of faith. We are always weak. But God is always strong! On our own, we are nothing, and wouldn’t have faith at all. But by God’s grace we believe, we have faith. It’s not a question of “how much”, therefore, but “in whom” we believe.
