To obey is better than sacrifice... (1 Samuel 15:22)
And why call ye me, Lord, Lord, and do not the things which I say? (Luke 6:46)
If ye love me, keep my commandments. (John 14:15)
If ye keep my commandments, ye shall abide in my love; even as I have kept my Father's commandments, and abide in his love. (John 15:10)
I, the Lord, am bound when ye do what I say; but when ye do not what I say, ye have no promise. (Doctrine and Covenants 82:10)
When we obtain any blessing from God, it is by obedience to that law upon which it is predicated. (Doctrine and Covenants 130:21)
We may rationalize our disobedience, but we cannot escape the consequences.
