One thing I gained in my life is just the need for more Jesus in my life. You never come to a place in your walk with Jesus where you feel like you've had enough. That's a dangerous feeling to have.
The greatest rewards come when you give of yourself. It's about bettering the lives of others, being part of something bigger than yourself, and making a positive difference.
I may have absolutely no control over what happens to us, but we can control how we respond. If we choose the right attitude, we can rise above whatever challenges we face.
Faith is walking by faith, not by what you feel. You are not always going to feel that Jesus loves you or that God is good, but you know He is. It is the up and down of the journey.
