The heart is the part of man which God chiefly notices in religion. The bowed head, and the bended knee–the grave face and the rigid posture–the ritual response, and the formal amen–all these together do not make up a spiritual worshiper. The eyes of God look further and deeper. He requires the worship of the heart. “My son,” he says to every one of us, “Give me your heart.” - J.C. Ryle

“Worship is giving God the best that He has given you. Be careful what you do with the best you have. Whenever you get a blessing from God, give it back to Him as a love gift. Take time to meditate before God and offer the blessing back to Him in a deliberate act of worship. If you hoard a thing for yourself, it will turn into spiritual dry rot, as the manna did when it was hoarded. God will never let you hold a spiritual thing for yourself; it has to be given back to Him that He may make it a blessing to others." - Oswald Chambers
"Depend on it, my hearer; you never will go to heaven unless you are prepared to worship Jesus Christ as God." - Charles Spurgeon
"Any man or woman on this earth who is bored and turned off by worship is not ready for heaven." - A.W. Tozer
