1 Corinthians 9:26-27 KJV
I therefore so run, not as uncertainly; so fight I, not as one that beateth the air: but I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.
Joel 2:28 KJV
And it shall come to pass afterward, that I will pour out my spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions:
Psalm 27:4 KJV
One thing have I desired of the LORD, that will I seek after; That I may dwell in the house of the LORD all the days of my life, To behold the beauty of the LORD, and to enquire in his temple.
Marriage reflects the sacred union of Christ and His Church (bride and groom). Homosexuality/same sex marriage on the other hand challenges God's design for this divine picture.
Ephesians 6:12
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
