What I do have I give to you

Acts 3:1-16
Peter with John healed the lame beggar at the gate of Temple that is called the Beautiful Gate.
"I have no silver and gold, but what I do have I give to you. In the name of Jesus Christ of Nazareth, rise up and walk" Peter said to him.
Peter addressed the people and witnessed Jesus Christ is raised from the dead: you denied the Holy and Righteous One, and killed the Author of life, whom God raised from the dead. To this we are witness.
Jesus Christ his name - by faith in his name-- has made this man strong whom you see and know, and the faith that is through Jesus has given the man this perfect health in the presence of you all.
Peter's message here is much the same in Chapter 2, calling his fellow-Israelite repentance and faith.
Why?
Peter has the sense that the Holy Spirit is with him so he said to the lame to him rise up and walk. The words was with power of Jesus Christ.
Healing and teaching, both made possible by the power of the Spirit of God, go together here, as they did in the ministry of Jesus.
What I do have I give to you is the essential motivation of follower of Jesus Christ. As Jesus what he has done for all of us.
How?
I found I am not so easy to do as peter has done, because I have some property. Please forgive my sin. I like to struggle for this target and get the life prize from the Lord.
