We aren’t saved to be mere mouthpieces for God; we’re saved to be his sons and daughters. God has no interest in turning his preachers into passive channels. He wants vigorous, alert, wide-awake men and women with all their powers and faculties intact. God’s disciples are spiritual messengers, not spiritual mediums, and the message they deliver must be part of themselves.
The Son of God was his message. His words were Spirit and life (John 6:63). As disciples, we must become the examples of what we preach; our lives must become the very sacrament of our message. It is natural to want to serve and give to others—that desire lies in most human hearts. But it takes a heart broken by the conviction of sin, sanctified by the Holy Spirit, and crumpled into the purposes of God to turn a life into the sacrament of its message.
There is a difference between giving testimony and preaching. Anyone who is saved can give testimony. A preacher is someone who has answered the call of God and is determined to use every power to proclaim God’s truth. God takes his preachers out of their own ideas for their lives and shapes them for his use, just as the disciples were after Pentecost. Pentecost did not teach the disciples anything; it made them the embodiment of their message: “You will be my witnesses” (Acts 1:8).
Before God’s message can liberate other souls, the liberation must be real in you. Gather the material you wish to preach, and set it alight. Let God have perfect liberty when you speak.
