As representatives of Jesus we should always be prepared to sow seeds of Christianity into the lives those we interact with and speak about Him to those who ask (1 Pet 3:15). Having a short, up-to-date testimony of God at work in your life can be powerfully used by the Holy Spirit to challenge or encourage another. It is not about our knowledge of, but our relationship with, the Lord, so our words should magnify Him, not us. While skeptics may argue about the existence of God or debate the validity of Scripture, no one can deny your personal experiences with Him, nor refute the transformation in your character. There is power in our testimony, even if our theology is incomplete (Jn 9:25; Rev 12:11).
Our walk should match our talk
of their response, or embarrassed and ashamed my living won’t match up to what I say? If my lifestyle and actions are deficient, what steps am I taking to bring them more into line with God’s standard? The Bible asks, how will they hear unless we tell (Rom 10:14)?
David spoke from personal experience with a bold, victorious testimony. As he recalled how God had helped him in the past, he confidently believed for a future victory (1 Sam 17:34-36). To speak to others about your faith will also ‘build you up’ as you tell what great things the Lord has done for you (Mk 5:19).
