There is a difference between giving a testimony and preaching. A preacher is someone who has received the call of God and is determined to use all his energy to proclaim God’s truth. God takes us beyond our own aspirations and ideas for our lives, and molds and shapes us for His purpose, just as He worked in the disciples’ lives after Pentecost. The purpose of Pentecost was not to teach the disciples something, but to make them the incarnation of what they preached so that they would literally become God’s message in the flesh. “…you shall be witnesses to Me…” (Acts 1:8).

Allow God to have complete liberty in your life when you speak. Before God’s message can liberate other people, His liberation must first be real in you. Gather your material carefully, and then allow God to “set your words on fire” for His glory.
