Chapter 13:31 and for many days He appeared to those who came up with Him from Galilee to Jerusalem, the very ones who are now His witnesses to the people.
Chapter 13:32 And we preach to you the good news of the promise made to the fathers,
Chapter 13:33 that God has fulfilled this promise to our children in that He raised up Jesus, as it is written in the second Psalm, ‘You are My Son; today I have begotten You.’
Chapter 13:34 As for the fact that He raised Him up from the dead, no more to return to decay, He has spoken in this way: ‘I will give you the holy and sure blessings of David.’
From Acts 1:3 we see that Jesus was seen for forty days and in I Corinthians 15:5-8 Paul tells us that He was seen by over five hundred brethren at one time. We also see in verse 31 that He was seen by the apostles and Paul speaks of the apostles being specifically chosen for this purpose. They were to be witnesses to the resurrection in order to talk with Him and also fellowship with Him, but most importantly, to be witnesses to the people. After this experience, is it any wonder, that the apostles went out to proclaim the resurrection of Jesus and put their lives on the line for this purpose? Then we see in verses 32-34, Paul and Barnabas speaking of the Good News of salvation through the death, burial, and resurrection of Jesus. To a Jew, nothing could be greater than the assurance that the Messiah had come and to a sinner, who recognizes his sin and sinfulness and who realizes the wages of sin is death, nothing could bring greater joy than the fantastic news of salvation by grace through faith in the finished work of Jesus!!!
