content: desiring no more than what one has; satisfied.
I'm making the decision to be content with my life. Not content as in "Yep, I'm good right here" and never want to strive for anything more but content as in "God, there are things I want in my life but I trust You with how and when they'll happen." Philippians 4:11-13 says, "I am not saying this because I am in need, for I have learned to be content whatever the circumstances. I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want. I can do everything through him who gives me strength (NIV)."
I think contentment (true contentment) is a by-product of faith in God. When you're content, you have this sense inside you that it's going to be ok; everything will work out so just enjoy the ride. I want to be content. I want to hand the steering wheel over to God while I either watch the scenery or take a nap. Why? Because I trust where He's taking me.
