Read Luke 7.
Jesus came to earth to be the perfect sacrifice, the only one who could take away the penalty for our sins, the only one to justify human beings before God. Jesus heals the servant of the centurion- not because the centurion was such a good guy but because the centurion (a gentile who would not have had a blood inheritance into the family of Israel) had faith in Him.
And Jesus went with them. When he was not far from the house, the centurion sent friends, saying to him, “Lord, do not trouble yourself, for I am not worthy to have you come under my roof. Therefore I did not presume to come to you. But say the word, and let my servant be healed. For I too am a man set under authority, with soldiers under me: and I say to one, ‘Go,’ and he goes; and to another, ‘Come,’ and he comes; and to my servant, ‘Do this,’ and he does it.” When Jesus heard these things, he marveled at him, and turning to the crowd that followed him, said, “I tell you, not even in Israel have I found such faith.” And when those who had been sent returned to the house, they found the servant well. Luke 7:6-10 (ESV)
Faith has a source as well as an object- Jesus is both the source of our faith and the object of it. Jesus raises the widow’s son, not as a witness to believers, but as testimony to those who do not have faith. In Jesus’ compassion He raised the young man. The Lord, the giver of life gave those who were blind to Him the evidence that proves He is Who He says He is.
And when the Lord saw her, he had compassion on her and said to her, “Do not weep.” Then he came up and touched the bier, and the bearers stood still. And he said, “Young man, I say to you, arise.” And the dead man sat up and began to speak, and Jesus gave him to his mother. Fear seized them all, and they glorified God, saying, “A great prophet has arisen among us!” and “God has visited his people!” And this report about him spread through the whole of Judea and all the surrounding country. Luke 7:13-17 (ESV)
At this time both Jesus and his cousin, John the Baptist were preaching and discipling people. John’s followers kept questioning John, “Are you the Messiah, or is there someone else?”
So John sent his followers to Jesus to find out if Jesus really was who He claimed to be.
And he answered them, “Go and tell John what you have seen and heard: the blind receive their sight, the lame walk, lepers are cleansed, and the deaf hear, the dead are raised up, the poor have good news preached to them. And blessed is the one who is not offended by me.” Luke 7:22-23 (ESV)
There were those who questioned John the Baptist as well as those who questioned Jesus. John was the last prophet, the one who was to make a highway in the wilderness.
For John the Baptist has come eating no bread and drinking no wine, and you say, ‘He has a demon.’ The Son of Man has come eating and drinking, and you say, ‘Look at him! A glutton and a drunkard, a friend of tax collectors and sinners!’ Yet wisdom is justified by all her children.” Luke 7:33-35 (ESV)
The fear of the Lord is the beginning of wisdom (Proverbs 9:10, Isaiah 11:12) The Pharisees had put their faith in outward appearances and works of the Law rather than putting all of their faith and trust in the Son of Man.
The “sinful woman” who came to Jesus washing His feet with her tears and drying them with her hair knew her desperate need for Jesus. She knew that her works condemned her. Our salvation is not in how well we can obey the Law or how good we can make ourselves look. Our salvation is entirely outside of ourselves.
The Bible speaks of salvation in the passive voice, a work that is done to us, and for us.
Luther teaches in the Small Catechism in his explanation of the Third Article of the Apostle’s Creed:
I believe in the Holy Spirit, the holy Christian church, the communion of saints, the forgiveness of sins, the resurrection of the body, and the life everlasting. Amen.
What does this mean?
I believe that I cannot by my own reason or strength believe in Jesus Christ, my Lord, or come to Him; but the Holy Spirit has called me by the Gospel, enlightened me with His gifts, sanctified and kept me in the true faith. In the same way He calls, gathers, enlightens, and sanctifies the whole Christian church on earth, and keeps it with Jesus Christ in the one true faith. In this Christian church, He daily and richly forgives all my sins and the sins of all believers. On the Last Day, He will raise me and all the dead, and give eternal life to me and all believers in Christ. This is most certainly true.
Faith is a gift. Jesus gives us the faith to trust in Him and in His sacrificial death on the cross for our salvation.
