Romans 15:2 “We should all be concerned about our neighbor and the good things that will build his faith.” (GW)
One thing that is important for all Christians to do is share stories of the wonderful things God has done for them, big or small. Doing so encourages others. It’s a good reminder that God still does miracles, big & small, for everyone. That reminder can be a blessing when times are tough & you feel like God doesn’t care.
I think sharing stories of God’s blessings is also good to do with non believers. For one thing, it encourages them that good things do happen even in the worst of times. For another, maybe telling them the story of your blessings will sow a seed in them. They may decide they want to know more about this God of yours. Wouldn’t that be a wonderful thing? In my experience before I was a Christian, I was more responsive to stories of God’s love than the Bible thumping, fire & brimstone types who told me I was going to hell. Stories of His love gently wooed me to God, while the “you’re going to hell if you don’t accept Jesus right now!” conversation pushed me far away. I believe most people are that way as well. Personally, I don’t witness in the traditional sense of that word. I tell people stories of miraculous & beautiful things God has done for me instead, & I find even die-hard atheists will at least listen to me without objection.
Also, sharing your stories encourages you too. It keeps the blessing close to your heart & reminds you that God loves you, even if for some reason you don’t feel His love. You can’t always count on others to encourage you, so you have to encourage yourself. What better way to do so than remembering the wonderful things God has done for you?
Telling such stories also increases your joy & your faith. While you’re blessing others, you’re also blessing yourself. How can you go wrong by sharing stories of your blessings?
