In supporting same sex marriage – advocating equal rights with male-female unions – you’re effectively declaring human civilization and development up to this point null and void. You’re opting out of the human covenant that only by becoming “one flesh” in real marriage can you procreate.
If you’re considering adoption, whatever you pass onto the next generation must be rooted and grounded in the word of God.
Remember whatever we’re doing, we’re modelling for the future what love, faith and hope looks like. Hate the sin, not the sinner because there is always the opportunity for repentance.
