Leviticus 18:26 You shall therefore keep my statutes and my judgments, and shall not commit any of these abominations; neither any of your own nation, nor any stranger that sojourns among you.
Now, we must be very careful with the word that is used in the above verses where it says abomination, for this does not mean that there is no hope for any such individual. There are other sins that are labeled as abominations too, and therefore, the salvation of God could, and would take care of all abominations wherever the criteria and prerequisites are met.
Proverbs 6:16 These six things doth the Lord hate: yea, seven are an abomination unto him. 17 A proud look, a lying tongue, and hands that shed innocent blood, 18 A heart that devises wicked imaginations, feet that be swift in running to mischief, 19 A false witness that speaks lies, and he that sows discord among brethren.
Therefore, family ties do not necessarily have to be severed just because of a same sex marriage; it just means that there are limits to which the Christian parents, and family members can safely go, without incurring the displeasure of God or without violating one’s conscience. And we will often discover in our sojourn down here on this earth, that there will be times when we will have to choose between our love for God, and love for family members. This is just the plain truth in its unadulterated form.
Matthew 10:33 But whosoever shall deny me before men, him will I also deny before my Father which is in heaven. 36 And a man's foes shall be they of his own household. 37 He that loveth father or mother more than me is not worthy of me: and he that loves son or daughter more than me is not worthy of me. 38 And he that takes not his cross, and follows after me, is not worthy of me.
May The Lord add His blessing to the study of His word. God bless!
