God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)
True happiness is to rejoice in the truth, for to rejoice in the truth is to rejoice in You, O God, who are the truth… Those who think that there is another kind of happiness look for joy elsewhere, but theirs is not true joy.
Doctrine matters. What you believe about God, the gospel, the nature of man, and every major truth addressed in Scripture filters down to every area of your life. You and I will never rise above our view of God and our understanding of His Word.
