Christ’s death for our sins is sometimes referred to as vicarious atonement. He took responsibility for us when we were incapable of atoning for ourselves. That is a wonderful fact and an essential concept that is basic to the Christian faith. If you want, you can read more about it here.
Now we are going to talk about something else — vicarious faith — an idea central to the Christian life. Needy people are not always in a position to believe. They may need us to step in for them and take the responsibility upon ourselves to believe. Our faith can stand in for their faith, our prayers for their prayers. Matthew 9 shows us an extreme case.
18 While he was saying these things to them, behold, a ruler came in and knelt before him, saying, “My daughter has just died, but come and lay your hand on her, and she will live.” 19 And Jesus rose and followed him, with his disciples. … 23 And when Jesus came to the ruler’s house and saw the flute players and the crowd making a commotion, 24 he said, “Go away, for the girl is not dead but sleeping.”And they laughed at him. 25 But when the crowd had been put outside, he went in and took her by the hand, and the girl arose. 26 And the report of this went through all that district.
The ruler came to Jesus on behalf of his daughter. She was dead. In the house was a lifeless, breathless and certainly faithless corpse. Her father reached out in faith when she was unable to believe for herself. The mourners were no help. Their expressions of grief were interrupted by their laughing at Jesus. But Jesus did what Jesus does and the girl arose. I want to exercise that kind of faith on behalf of others.
