Gods laws are unchanging, but our understanding of them will change as we learn discernment.
The time will come when it will be a matter of medical knowledge what causes homosexuality, and it will also be a matter of spiritual knowledge about how and where gays fit into the plan, because God will reveal it. When he does, we will discover that our heavenly father is more liberal and generous in his designs than we imagine and more liberal and generous in his judgments than we can imagine. If we are to become like Him, can we do any less?
But, now we are commanded to love (love without understanding all reasons), to forgive (forgive without imposing conditions), and not play the role of the accuser, and not dig a pit for our neighbor, nor make a man an offender for a word. If we do not believe and practice these commandments, now, while our faith is being tested, we will not believe and practice these commandments when our knowledge is more complete. And, at that time, if we have not learned to love, we sill stand ashamed and condemned for our lack of faith and charity.
“If you do it unto the least among you, you have done it unto me.” The least among us is he whom we esteem to be the least among us: the greatest sinner, the most irritating person in your life. Instead of being your enemy or somebody you would overlook, see him as you Savior. See him as coming to you with a lesson in his hands.
