26 A week later his disciples were again in the house, and Thomas was with them. Although the doors were shut, Jesus came and stood among them and said, "Peace be with you." 27 Then he said to Thomas, "Put your finger here and see my hands. Reach out your hand and put it in my side. Do not doubt but believe." 28 Thomas answered him, "My Lord and my God!" 29 Jesus said to him, "Have you believed because you have seen me? Blessed are those who have not seen and yet have come to believe."
30 Now Jesus did many other signs in the presence of his disciples, which are not written in this book. 31 But these are written so that you may come to believe that Jesus is the Messiah, the Son of God, and that through believing you may have life in his name.

That one day in seven should be religiously observed, was an appointment from the beginning. And that, in the kingdom of the Messiah, the first day of the week should be that solemn day, was pointed out, in that Christ on that day once and again met his disciples in a religious assembly. The religious observance of that day has come down to us through every age of the church. There is not an unbelieving word in our tongues, nor thought in our minds, but it is known to the Lord Jesus; and he was pleased to accommodate himself even to Thomas, rather than leave him in his unbelief. We ought thus to bear with the weak, 1 John 5:11.

There were other signs and proofs of our Lord's resurrection, but these were committed to writing, that all might believe that Jesus was the promised Messiah, the Saviour of sinners, and the Son of God; that, by this faith, they might obtain eternal life, by his mercy, truth, and power. May we believe that Jesus is the Christ, and believing may we have life through his name.
