God desires sacrifice and obedience, not a religious game. It must be emphasized that our obedience is not for the purpose of saving us—salvation is by grace—but to assist us in perfecting holiness (II Corinthians 7:1) and to provide a witness of God working in our lives (Matthew 5:16).
Israel's purely ceremonial religion could never safeguard the truth because the people were not living it. By being used in the worship of manmade deities, not the Creator God, the rituals of their shrines were completely divorced from the truth found in the law. God will not be mocked (Galatians 6:7). The evidence of true religion is that through His correction in mercy and love, it will touch and purify every area of life. If we are really in contact with the true God, change will take place gradually as we grow.
To determine if our profession and practice of religion is pleasing to God, we must consider two questions: 1) Are we covered by the blood of Jesus Christ? and 2) Are we obeying God to the best of our understanding?
We never obey to the extent of our knowledge because knowledge, knowing what God expects, always outpaces ability. We gather knowledge before we have the ability to live it, and that makes us feel guilty because we realize we are not applying what we know. This guilty feeling is not really wrong, for without guilt we would not change. It is good if it makes us change, but when guilt becomes neurotic, it becomes destructive and wrong.
Today, psychologists are trying to remove guilt from our every thought, word, and deed—a sure sign of widespread spiritual poverty and complacency. But God says we can worship Him with a pure conscience because we know we have been cleansed of our past sins through Christ's sacrifice, and because we know God is faithful to us as we live by faith in Him (Hebrews 10:19-23).
