Even though you are armed with the teachings of Christ, do you feel deficient or ill-equipped in your witness for Christ in this world?  Perhaps you might be tempted to think that you are in charge of carefully strategizing how to make the gospel relevant to someone.  Along those lines, sometimes the idea of trying to find an area of personal suffering or difficulty is put forth as necessary.  But’s let’s try to make this as clear and simple as possible—if a person is currently living and breathing and has rationale capabilities, then that person sins against God and therefore the gospel is automatically relevant for that person.
So certainly, we know cannot change anyone’s heart, but do we not have at our disposal the very thing that can?  Let me remind us of a text we looked at a few weeks ago—2 Tim. 3:16 All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, 17 that the man of God may be complete, equipped for every good work.
Because the Word came from God and is used by God, the Christian is fully equipped for the ministry God has called them to.  This is how Paul thought about ministry and always implemented ministry, as seen in Acts 13.
