1 Timothy 4:15-16
New International Version (NIV)
15 Be diligent in these matters; give yourself wholly to them, so that everyone may see your progress. 16 Watch your life and doctrine closely. Persevere in them, because if you do, you will save(A) both yourself and your hearers.
I've also, at times, surrendered to the myth that loudness about the Gospel is better. There are times I'm so in love with God that I want to shout it out at the top of my lungs! I sing the song "Shout It Out!" and I want to do just that!
But while I think God does enjoy my enthusiasm, those who are watching me and listening to me will hear me more clearly if I speak with my actions. If time and repetition show that I'm being constant in my faith (and not just screaming like a banshee after an awesome mission trip), I'll be more likely to "save" people for a better life - the one that I'm trying to live in a closer relationship with God.
Until Everyone Hears,
