God's Word says in Philippians 4: 11-13 (MSG) (this is Paul speaking) Actually, I don't have a sense of needing anything personally. I've learned by now to be quite content whatever my circumstances. I'm just as happy with little as with much, with much as with little. I've found the recipe for being happy whether full or hungry, hands full or hands empty. Whatever I have, wherever I am, I can make it through anything in the ONE who makes me who I am.
The bottom line is, that, it is only in Jesus Christ that one finds true contentment. We cant find it in things, people or circumstances.
