You deal with doubt all the time. You have to choose to believe God in every situation. I remind myself all the time, get out of fear. Get out of doubt. Get back in faith.
Our problems are God's opportunities.
If you will do what you CAN do, God will do what you CANNOT do.
Forgiveness is not a feeling - it's a decision we make because we want to do what's right before God.
You will never enjoy life if you do not enjoy yourself.
A relationship with Christ changes your heart. It's not about your head. It changes your heart. Jesus comes to live in your heart, and even if a person does good works, but they do them without Christ, most of the time, their motives are wrong for why they do them.
