Do you ever get up in the morning, and you have your quiet time, and feel the presence of God, and you’re studying the Word, and God seems to speak to you, and you go out and you witness to everybody, and you’re obedient, and, boy, you just did it right that day. I mean, you were just on top of the world. You loved your wife, you didn’t kick the cat, you’re just—you’re walking with God. And you’re so full of joy at the end of the day.
And the next day you get up; well, you overslept, you shouldn’t have watched that program the night before, you should’ve been in the word, you didn’t witness when you had an opportunity, and there’s a real sense in which you’re filled with sorrow.
Do you know what that is? Idolatry. You have become the source of your own joy. Your joy comes from you and your continuous work. My joy comes from the finished work of Jesus Christ.
