The key to a full and healthy spiritual life is to put the word of God in its proper place. Unfortunately, as our world becomes darker, the Church is growing darker too. Homosexuality is an especially obvious example.
How many of you can tell me where Jesus addressed homosexuality? None of you. When questioned on divorce, Jesus defined marriage as one man and one woman for life, just like Adam and Eve, but Jesus was never actually asked about whether or not homosexuality is a sin, and so He never explicitly stated homosexuality is a sin. And so, tragically, many Christians take that as an excuse to either ignore, or even come on the wrong end of the issue.
But just because Jesus never explicitly said homosexuality is a sin does not mean He did not address it. In Romans 1, for example, Paul describes homosexuality as an unnatural lust, particularly one that results from a rejection of God, and that results in a judgement by God. "But that's Paul, not Jesus", the skeptic replies. And this is exactly what I'm talking about.
In Christianity, there is no meaningful distinction between the words Jesus spoke with His human mouth and the words He guided the prophets and apostles to write with their hands. I fear this may be an issue with what's called "red letter" Bibles. We've now got it into our minds that somehow, only the red letters, symbolising Jesus speaking, are important. But the truth is they're inseparable. In fact, more often than not, it's impossible to understand the red letters without understanding the black. And, as in the above example, the red letters often confirm the black. When Jesus was questioned on divorce, He didn't bring a brand new revelation, He went back and affirmed the authority of the Old Testament.
Nothing in Genesis is in red letters. Jesus was there (John 1:1), but Jesus had not yet been born to our world as a child, and so even in a red letter Bible, Genesis is entirely in black. And yet this is what Jesus appealed to. Jesus even said that believing Moses is essential to believing Him (John 5:45-46). And yes, that's in red letters.
This is because of the inspiration of the scriptures. The scriptures are not just something men made up as they went along, they are the very words of God (2 Timothy 3:15-17; 2 Peter 1:20-21). Thus, every time you claim Jesus as your authority, you are claiming to believe all of the scriptures. Every time you then proceed to dismiss those scriptures, whether on the issue of homosexuality, or on any other issue, you are disproving your claim to be relying on Jesus. Put the scriptures in the same place as you put Jesus, because they are His words, as surely as if He was stood in front of you reciting them to you.
