To obey is better than sacrifice
Worship is not some slow, beautiful song; it is obedience. No matter how we “perform” in church our ministry, our serving , if we do not obey God in our daily lives, we are not worshiping Him and are, in fact, living in adultery. John Bevere
Adultery is much more than sex outside your marriage with someone other than your wife or husband. It had to be difficult for the crowd when Jesus proclaimed “But now I tell you: anyone who looks at a woman and wants to possess her is guilty of committing adultery with her in his heart.” Jesus understood adultery begins long before the physical act occurs.
Faithfulness is a matter of who your heart belongs to. When we allow disobedience in our lives we are unfaithful to the One who deserves our worship and even more seriously when a believer knows the will of God, yet intentionally chooses their own desires instead, that is idolatry.
