Personal recommendation is the best means of advertising anything and the most likely way of others accepting it. Daily living recovery is of more value to influencing others than debate or strong arguments.
Testimony is convincing when demonstrated in consistent living in accordance with what we say. It is a case of our life telling the truth and manifesting both the reality of what has transposed within us as well as the depth of our inner change.
Are we a good advertisement of what we confess? What is my life witness recommending to others?
2 Corinthians 4:2 We have turned away from secret and shameful ways. We don’t use trickery, and we don’t change the teaching of God. We teach the truth plainly. This is how we show people who we are. And this is how they can know in their hearts what kind of people we are before God.
