John 21; Acts 1
Jesus commanded His Disciples to go back to Jerusalem and wait for the promise of the Father, the Baptism with the Holy Spirit. He said they would receive power … power to be effective witnesses of Christ to the entire world.
If you feel you are lacking in God’s power to tell others about Christ, begin seeking this baptism. I remember when I did, when I was a teenager. I knew I wanted it. I would pray and ask the Lord for the infilling when I laid upon my bed at night. I eventually received the infilling with the evidence described in Acts 2.
I have enjoyed a boldness to witness ever since then. God’s Spirit living within us is an empowering that gives us supernatural assistance to make His power known to others.
