The following are some common objections to God’s commands against sexual immorality:
1. It’s not wrong if we love each other.
The Bible makes no distinction between “loving” and “unloving” sexual relations. The only biblical distinction is between married and unmarried people. Sex within marriage is blessed (Genesis 1:28); sex outside of marriage is “fornication” or “sexual immorality” (1 Corinthians 7:2–5).
2. Times have changed, and what was wrong in biblical times is no longer considered sin.
Most of the passages condemning sexual immorality also include evils such as greed, lust, stealing, etc. (1 Corinthians 6:9–10; Galatians 5:19–21). We have no problem understanding that these other things are still sin. God’s character does not change with culture’s opinion (Malachi 3:6; Numbers 23:19; Hebrews 13:8).
3. We’re married in God’s eyes.
This argument implies that God is cross-eyed. The fallacy of this idea is that the God who created marriage in the first place would retract His own command to accommodate what He has called sin. God declared marriage to be one man and one woman united for life (Mark 10:6–9). The Bible often uses the imagery of a wedding and a covenant marriage as a metaphor to teach spiritual truth (Matthew 22:2; Revelation 19:9). God takes marriage very seriously, and His “eyes” see immorality for what it is, regardless of how cleverly we have redefined it.
4. I can still have a good relationship with God because He understands.
Proverbs 28:9 says, “If one turns away his ear from hearing the law, even his prayer is an abomination.” We fool ourselves when we think that we can stubbornly choose sin and God does not care. First John 2:3–4 contains a serious challenge for those who persist in this line of thinking: “We know that we have come to know him if we keep his commands. Whoever says, ‘I know him,’ but does not do what he commands is a liar, and the truth is not in that person.”
Hebrews 13:4 makes God’s expectation for His children crystal clear: “Let marriage be held in honor among all, and let the marriage bed be undefiled, for God will judge the sexually immoral and adulterous.” Sexual immorality is wrong. The blood of Jesus can cleanse us from every type of impurity when we repent and receive His forgiveness (1 John 1:7–9). But that cleansing means our old nature, including sexual immorality, is put to death (Romans 6:12–14, 8:13). Ephesians 5:3 says, “But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God’s holy people.”
