You may say, “But I have given my promise, and shall I now retract it?” I answer, If you have made a promise contrary to the Scriptures, by all means retract it without delay, and in humility before God repent of the infatuation that led you to make so rash a pledge. Far better take back such a promise, in the fear of God, than keep it, and thereby dishonor your Maker. MYP 441.2
Remember, you have a heaven to gain, an open path to perdition to shun. God means what He says. When He prohibited our first parents from eating the fruit of the tree of knowledge, their disobedience opened the floodgates of woe to the whole world. If we walk contrary to God, He will walk contrary to us. Our only safe course is to render obedience to all His requirements, at whatever cost. All are founded in infinite love and wisdom.—Testimonies for the Church 5:361-365. MYP 442.1
