Have you responded to the Gospel Call? Have you received forgiveness from Jesus Christ? Have you called on the Name of the Lord to be Saved?
Have you responded to the conviction of the Holy Spirit to totally devote your life and energy to knowing the Lord Jesus Christ? Have you re-prioritized your life according to the Gospel?
Have you responded to the call to ministry? You are gifted and empowered by the Holy Spirit to do a ministry in a local church and in the world. Do you believe that? Are you living that out?
Since receiving Christ as Savior, have you started to see God, yourself, and other people differently?
Pray that God would give you the call and that you'd have the heart to respond.
