My feelings are not God. God is God. My feelings do not define truth. God’s word defines truth. My feelings are echoes and responses to what my mind perceives. And sometimes - many times - my feelings are out of sync with the truth. When that happens - and it happens every day in some measure - I try not to bend the truth to justify my imperfect feelings, but rather, I plead with God: Purify my perceptions of your truth and transform my feelings so that they are in sync with the truth.
John PiperAdjust your doctrine - or just minimize doctrine - to attract the world, and in the very process of attracting them, lose the radical truth that alone can set them free.
John PiperSin is what you do when your heart is not satisfied with God. No one sins out of duty. We sin because it holds out some promise of happiness. That promise enslaves us until we believe that God is more to be desired than life itself (Psalm 63:3). Which means that the power of sin's promise is broken by the power of God's.
John PiperThe engagement of the heart in worship is the coming alive of the feelings and emotions and affections of the heart. Where feelings for God are dead, worship is dead.
John Piper
