26 Eight days later the disciples were together again, and this time Thomas was with them. The doors were locked; but suddenly, as before, Jesus was standing among them. "Peace be with you," he said. 27 Then he said to Thomas, "Put your finger here, and look at my hands. Put your hand into the wound in my side. Don't be faithless any longer. Believe!" 28 "My Lord and my God!" Thomas exclaimed. 29 Then Jesus told him, "You believe because you have seen me. Blessed are those who believe without seeing me."
30 The disciples saw Jesus do many other miraculous signs in addition to the ones recorded in this book. 31 But these are written so that you may continue to believe that Jesus is the Messiah, the Son of God, and that by believing in him you will have life by the power of his name.

(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.
