Doing the right thing isn't always the thing that makes us feel good at the moment. Many of the things God has called us to do require us to go against our feelings for the moment. But, you see the Christian knows that actions lead, feelings follow. God loved us so much that He gave His Son. The right thing isn't always the thing that feels good at the moment.
Actions lead, feelings follow.
The joy followed the cross. It didn't come prior or during. Likewise, the good feelings that result from our doing right usually come after the act, not before. If we wait around in the beginning, hoping to get our feelings to go along with our actions, we'll seldom do what is right. Welcome to the world of discipleship.
