Sometimes, we can feel like we "have to" serve God or something bad will happen.
While the Christian life does have been, we should change our hearts.
We should say that we get to love God because He first loved us.
The Creator of all Heaven and Earth wants personal relationship with us!
We should delight in God's goodness and love towards us.
This is not to receive a reward but just because God is that good to us, better than we are to ourselves.
Then when we take delight in the Lord, we will experience the desires of our hearts being realized.
But this starts with enjoying the Lord, just because He is good to us.
