This was an interesting passage I ran across recently.
1 Thessalonians 4:1-8
1 Finally then, brethren, we request and exhort you in the Lord Jesus, that as you received from us instruction as to how you ought to walk and please God (just as you actually do walk), that you excel still more. 2 For you know what commandments we gave you by the authority of the Lord Jesus. 3 For this is the will of God, your sanctification; that is, that you abstain from sexual immorality; 4 that each of you know how to possess his own vessel in sanctification and honor, 5 not in lustful passion, like the Gentiles who do not know God; 6 and that no man transgress and defraud his brother in the matter because the Lord is the avenger in all these things, just as we also told you before and solemnly warned you. 7 For God has not called us for the purpose of impurity, but in sanctification. 8 So, he who rejects this is not rejecting man but the God who gives His Holy Spirit to you.
So many times, people want to accept some sin and reject others. Some will say to not have homosexual sex, while the ignore people who have sex outside of marriage. In fact, this command refers back to the moral code of the Old Testament – we must not sin sexually – in any way that God has said not to! While this includes homosexual sex, it also includes incest, people you are not married to, and bestiality (Leviticus 18).
There’s a lot of forbidden sex. One should not commit adultery (Genesis 20:1-7; Deuteronomy 5:18; Hebrews 13:4; Proverbs 23:26-27).
One should not have sex with people of the same gender (Leviticus 18:22; 20:13; Romans 1:26-27; 1 Corinthians 6:9-10). One should not have sex with animals (Exodus 22:19; Leviticus 18:23, 20:15-16). One should not have sex with people to whom you are related (other than your husband or wife) (Leviticus 18:6-15; 20; Deuteronomy 27:20-23; 1 Corinthians 5:1-13). This means to not have sex with a close relative (Leviticus 18:6), with your sister/brother (Leviticus 18:9, 20:17; Deuteronomy 27:22), with your grandson/granddaugher (Leviticus 18:10), with your aunt/uncle (Leviticus 18:12-13; 20:19-20), with your daughter-in-law (Leviticus 18:15), your father’s wife (Leviticus 20:11; 27:20; 1 Corinthians 5:1-13), your wife’s mother (Leviticus 18:14; Deuteronomy 27:23), your brother’s wife (Leviticus 18:16), your wife’s granddaughter (Leviticus 18:17), your wife’s sister , while your wife is living (Leviticus 18:18) – basically any close relative by blood or marriage.
Seuxal immorality is contrary to sound doctrine and is one of the things we are to leave behind when we become Christians (Colossians 3:4-7; 1 Timothy 1:9-11). The people of Sodom and Gomorrah were sexually immoral and were judged for it (Jude 1:6-8). There should be no one who calls themselves Christ’s who is sexually immoral (Ephesians 5:2-4; Hebrews 12:15-17). We are not even to associate with the sexually immoral (1 Corinthians 5:10-12). God gives people an opportunity to repent from sexual immorality (), but God will judge and punish those who are sexual immoral (1 Corinthians 10:7-9; Hebrews 13:3-5; Revelation 2:19-21; Revelation 9:20-21; Revelation 21:7-9′ Revelation 22:14-16). Indeed, God goes on to say that the sexually immoral will not inherit the kingdom of God (1 Corinthians 6:9-10; Galatians 5:19-21).
We should be in control of ourselves – we are not animals who can not (or will not) control themselves. We are God’s people – we are to be holy as God is holy (1 Peter 1:16). This is one of the reasons God has given marriage – to prevent sexual immorality (1 Corinthians 7:2-5; 1 Thessalonians 4:3-5).
Realize there is a major warning here - by rejecting this instruction, you reject God. This is not something to be taken lightly. We must look to God and not indulge ourselves. We must be holy, and this is one area of holiness which God haas mentioned a lot. So it must be both common and a definite no-no. Control yourself, Christian! Be God’s person and do not disobey God, or suffer the consequences – both in this life and in the afterlife.
