If Christian living is not enjoyable, if prayer is not a pleasure, if service is not our joy, we are in trouble at the heart of our Christian walk. There are many verses that speak to this. Here are two:
“If you obey my commands, you will remain in my love, just as I have obeyed my Father’s commands and remain in his love. I have told you this so that my joy may be in you and that your joy may be complete.” ( John 15:10-11)
There is an incredible promise related to enjoying God:
Delight yourself in the LORD and he will give you the desires of your heart. Psalms 37:4
It is easy to read this verse and concentrate on the last part. That is what we want, to get the desire of our heart. But it is almost impossible to delight in the Lord when our motive is to receive the desire of our heart. The want of our own desires keeps us from delighting in Him.
If a person does begin to delight in the Lord, God will surely fulfill His promise. He will give him the desire of his heart. There is a subtle temptation at this point that prevents many from enjoying God over the long haul. We delight in God; He gives us the desire of our heart; we begin to delight in the gifts He gives; we cease delighting in the Lord. We are delighting in the things He provides.
