Richard Baxter, in A Christian Directory (Ligonier, 1990), page 140, lists seven benefits of delighting ourselves in God. Updating the language a little:
1. Delight in God will prove that you know him and love him and that you are prepared for his kingdom, for all who truly delight in him shall enjoy him.
2. Prosperity, which is merely the small addition of earthly things, will not easily corrupt you or transport you.
3. Adversity, that is, the withholding of earthly delights, will not much grieve you or easily deject you.
4. You will receive more profit from a sermon or good book or conversation you delight in, than other people, who don’t delight in them, will receive from many such opportunities.
5. All your service will be sweet to yourself and acceptable to God; if you delight in him, he certainly delights in you (Psalm 149:4; 147:11; 1 Chronicles 29:17).
6. You will have a continual feast with you, to sweeten all the crosses of your life and provide you with joy greater than your sorrow in your saddest condition.
7. When you delight in God, your created pleasures will be sanctified to you and warranted in their proper place, which in other people are idolatrous or corrupt.
Lord, “you are good and you do good” (Psalm 119:68).
