The choice between belief and disbelief is a personal conviction that what somebody has told you is true, because you trust them.  Even seeing the evidence is sometimes insufficient.  The women had been convinced of the resurrection because the angels explained the empty tomb by reminding them of what Jesus had said, "The Son of Man must be delivered into the hands of sinful men, be crucified and on the third day be raised again." (Luke 24:7).  It was the reminder of Jesus’ words which took them from confusion to faith, because they came back to trusting Jesus and what He had said.
 
On the other hand, the disciples did not believe the women.  Their story did not make any sense to the men, who refuted any suggestion of resurrection.  Peter, ever curious, decided to see for himself.  He had the same experience as the women: he entered the empty tomb and saw the strips of linen, which had been wrapped around the body of Jesus, still wound together but the body had gone.  Yet he still did not believe that Jesus had been raised and had no answer to the question, ‘What has happened to the body of Jesus?’ because he had not believed the prophets or Jesus (Luke 24:25).
 
The difference between the women's conclusion and that of the disciples, including Peter, was that the women were reminded of what Jesus had said and they believed Him.  His words put their experience into perspective, explained what they observed and gave them hope.  It was to be the pattern for faith.  Signs and wonders can only draw people's attention to what God is doing, but without God's revelation the signs alone cannot make sense.  That is why God's Word remains essential if we are to start trusting Jesus and continue to walk in faith.  We then measure our experience by what He has revealed of Himself, and hold onto His written promises because we believe He is trustworthy (Psalm 56:4).

However, Christians who measure their faith by what they experience are bound to be disappointed and confused - they will not have the confidence to persist in the face of difficulties.  Instead, trust God's character, believe His words in the Bible and trust what He has promised (short term and long term); then live in obedience to Him (Proverbs 3:5).  That is the only way to live the life of faith.  One of the greatest acts of kindness to another Christian, at home or at work, is to encourage them to do the same.
