Today during staff meeting at the church, one of the pastors read this passage from Philemon 4-7, "I always thank my God as I remember you in my prayers, because I hear about your faith in the Lord Jesus and your love for all the saints. I pray that you may be active in sharing your faith, so that you will have a full understanding of every good thing we have in Christ. Your love has given me great joy and encouragement, because you, brother, have refreshed the hearts of the saints." NIV
The bolded part really stood out to me as I listened to him read. In sharing my faith, I am the one who comes to a full understanding of everything I have in Christ. In sharing with others, I am constantly reminded, I constantly re-hear the story, and I constantly re-learn all that God in Christ has done for me.
Evangelism is as much about God reaching other people through me as it is about God reminding me of all He has done for me.
I don't think the NLT interprets the last part correctly, but it does interpret the sharing of the faith as a sharing of generosity. When I share my faith, I remember.
