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 PiperThe Bible is the ultimate authority and infallible, not the pastor and not the elders. And it doesn't mean that you believe everything he says without examining it.
John PiperNot going to God because your faith is weak is like not going to the doctor because you feel sick.
John PiperA Christian is not a person who believes in his head the teachings of the Bible. Satan believes in his head the teachings of the Bible! A Christian is a person who has died with Christ, whose stiff neck has been broken, whose brazen forehead has been shattered, whose stony heart has been crushed, whose pride has been slain, and whose life is now mastered by Jesus Christ.
