Real life experience is hard to beat. Told the right way, real life experiences will connect your hearts in a way that you’re hoping for.
Likewise telling the story well of what God has done in your life, and how he’s still at work in you, is one of your greatest tools in sharing your faith. No one can argue with your real life experience.
If we can learn to consistently share how God is at work in our lives with non-believers, it can be the most significant thing God uses to bring them to himself. Unfortunately though, most of us limit sharing these things with other Christians.
