It is Jesus' name and the faith

Acts 3:11-24
Peter speak to onlookers(圍觀). It is Jesus' name and the faith that comes through him that has completely healed him, as you can all see.
Moses said, ‘The Lord your God will raise up for you a prophet like me from among your own people; you must listen to everything he tells you. 23 Anyone who does not listen to him will be completely cut off from their people."(Deut. 18:15,18,19)
And you are heirs of the prophets and of the covenant God made with your fathers. He said to Abraham, ‘Through your offspring all peoples on earth will be blessed.(Gen. 22:18; 26:4)
Peter read the scripture and says to crowd, this is how God fulfilled what he had foretold through all the prophets, saying that his Messiah would suffer. Repent, then, and turn to God, so that your sins may be wiped out, that times of refreshing may come from the Lord.
Why?
Jesus be suffering on the cross and God raised Him up. All of these are described by the prophets. So repent and turn to God is the only way to get rid of sins.
Peter spoke the right word at the right time.
Can I say the right word at the right time, I need God's Spirit and say the right word at right time.
How?
Ask the Lord to give me the wisdom and faith to honor his Holy Name.
