26 Eight days later, his disciples were again in the room. This time Thomas was with them. Jesus came through the locked doors, stood among them, and said, "Peace to you." 27 Then he focused his attention on Thomas. "Take your finger and examine my hands. Take your hand and stick it in my side. Don't be unbelieving. Believe." 28 Thomas said, "My Master! My God!" 29 Jesus said, "So, you believe because you've seen with your own eyes. Even better blessings are in store for those who believe without seeing."
30 Jesus provided far more God-revealing signs than are written down in this book. 31 These are written down so you will believe that Jesus is the Messiah, the Son of God, and in the act of believing, have real and eternal life in the way he personally revealed it.

(Read John 20:26-29)
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.
