Jesus said: I am the way, the truth, and the life: no man cometh unto the Father, but by me
Romans 10:9
“That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.”
Many will have heard of the expression "doubting Thomas".
This refers to the occasion when, after His death on the cross and resurrection, Jesus came to His disciples, but Thomas was not with them.
When the other disciples told Thomas that they had seen Jesus, he said to them "Except I shall see in his hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into his side, I will not believe" (John 20:25)
When Jesus came again to the disciples he invited Thomas to do just this. Thomas then believed and said to Him "My Lord and my God" (John 20:28)
This incident shows the patience and compassion of Jesus towards Thomas, but it also demonstrates to us that Jesus, after suffering and dying upon the cross, truly and physically rose from the dead, and is indeed the very Son of God and the only Saviour of sinners:
“...if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.” (Romans 10:9)
