As children of God, we have been given the wonderful gift of choice. The truest happiness and peace we can have comes by choosing to obey His laws. Disobedience to the Lord’s commandments will always deprive us of His blessings. The world changes constantly and dramatically, but God, His commandments, and promised blessings do not change. They are immutable and unchanging,” says Elder L. Tom Perry of the Quorum of the Twelve Apostles.
