Early on the first day of the week, while it was still dark, Mary Magdalene went to the tomb and saw that the stone had been removed from the entrance. So she came running to Simon Peter and the other disciple, the one Jesus loved, and said, “They have taken the Lord out of the tomb, and we don’t know where they have put him!”|
John 20:1-2 New International Version (NIV)

So Peter and the other disciple started for the tomb. Both were running, but the other disciple outran Peter and reached the tomb first. He bent over and looked in at the strips of linen lying there but did not go in. Then Simon Peter came along behind him and went straight into the tomb. He saw the strips of linen lying there, as well as the cloth that had been wrapped around Jesus’ head. The cloth was still lying in its place, separate from the linen. Finally the other disciple, who had reached the tomb first, also went inside. He saw and believed. (They still did not understand from Scripture that Jesus had to rise from the dead.) Then the disciples went back to where they were staying.
John 3:3-9 (NIV)

From that time on Jesus began to explain to his disciples that he must go to Jerusalem and suffer many things at the hands of the elders, the chief priests and the teachers of the law, and that he must be killed and on the third day be raised to life.
Matthew 16:21 (NIV)

At this, she turned around and saw Jesus standing there, but she did not realize that it was Jesus. He asked her, “Woman, why are you crying? Who is ti you are looking for?” Thinking he was the gardener, she said, “Sir, if you have carried him away, tell me where you have put him, and I will get him.” Jesus said to her, “Mary.” She turned to him and cried out in Aramaic, “Rabboni!” (which means “Teacher”).
John 20:14-16 (NIV)

Jesus calls you by name.

Again Jesus said, “Peace be with you! As the Father has sent me, I am sending you.” And with that he breathed on them and said, “Receive the Holy Spirit. If you forgive anyone’s sins, their sins are forgiven; if you do not forgive them, they are not forgiven.”
John 20:21-23 (NIV)

Now Thomas (also known as Didymus), one of the Twelve, was not with the disciples when Jesus came. So the other disciples told him, “We have seen the Lord!” But he said to them, “Unless I see the nail marks in his hands and put my finger where the nails were, and put my hand into his side, I will not believe.”
John 20:24-25 (NIV)

Then Thomas (also known as Didymus) said to the rest of the disciples, “Let us also go, that we may die with him.”
John 11:16 (NIV)

A week later his disciples were in the house again, and Thomas was with them. Though the doors were locked, Jesus came and stood among them and said, “Peace be with you.” Then he said to Thomas, “Put your finger here; see my hands. Reach out your hand and put it into my side. Stop doubting and believe.” Thomas said to him, “My Lord and my God!” Then Jesus told him, “Because you have seen me, you have believed; blessed are those who have not seen and yet have believed.”
John 20:26-30 (NIV)

Faith
Not some vague feeling or logical decision
An open acceptance and trust of God in Jesus
Not the opposite of doubt — it’s the opposite of fear
