God's truth has its own inbuilt power. We cannot force people to believe in Jesus - trust grows as they discover that Christ is trustworthy. Our task is to explain who Jesus is and what He has done, so that others will be persuaded to take action, by repenting and turning to follow Him. So, we need to answer questions about our faith and the reason we behave differently, and to do so gently and respectfully. If it is not obvious that we respect the questioner, how will they know that God loves them: and if we do not win their trust, why should we expect them to trust the Lord?
