Clearly his disciples took a long time to be persuaded completely of his nature. 

It was a new day when Jesus rose from the dead and all the previous teachings, miracles and experiences had not guaranteed their understanding.  I wonder how persuaded we are when presented with the words of Christ?

Luke 24:
 1 On the first day of the week, very early in the morning, the women took the spices they had prepared and went to the tomb. 2 They found the stone rolled away from the tomb, 3 but when they entered, they did not find the body of the Lord Jesus. 4 While they were wondering about this, suddenly two men in clothes that gleamed like lightning stood beside them. 5 In their fright the women bowed down with their faces to the ground, but the men said to them, "Why do you look for the living among the dead?     6 He is not here; he has risen! Remember how he told you, while he was still with you in Galilee: 7 'The Son of Man must be delivered into the hands of sinful men, be crucified and on the third day be raised again.' “8 Then they remembered his words.
 9 When they came back from the tomb, they told all these things to the Eleven and to all the others. 10 It was Mary Magdalene, Joanna, Mary the mother of James, and the others with them who told this to the apostles. 11 But they did not believe the women, because their words seemed to them like nonsense.     12 Peter, however, got up and ran to the tomb. Bending over, he saw the strips of linen lying by themselves, and he went away, wondering to himself what had happened.

None of Jesus’ followers questioned the reality of His death.  With their own eyes they had observed his suffering on the cross and knew the details of his body being put in the tomb.  In spite of everything else he said and did, this inevitability did not require any persuasion.  They knew He was dead.

When the women entered the empty tomb, they began to question what had happened.  His dead body was here, but now an empty sepulcher.

The angels asked why they were looking for the living among the dead.  Even though Jesus had foretold his death, burial and resurrection they had not grasped this part of his message.  They probably thought he referred to their Jewish understanding of resurrection; that all would be resurrected at the end of time.  But this was beyond their comprehension. 

Jesus had literally raised people from the dead, but they were still in shock at his empty tomb.  The angels reminded them that Jesus had told them what would happen.  Don’t you remember what he told you? 

Sometimes being told something repeatedly does little to persuade us.    Some of our struggles may come from not accepting what God has said.  When you are persuaded that God has spoken and are willing to commit everything into God’s care, there is a notable difference.  You are able to endure with faith in God to ultimately save you.

Jesus had in fact spoken of his death, burial and resurrection on several occasions.  Matthew, Mark and Luke all report multiple conversations where Jesus spoke clearly of this.

What does it take to be persuaded of truth?  The disciples were not easily convinced.  They may have followed Jesus, but they were not about to lose their own discretion and opinions.
