4 Marriage should be honored by all, and the marriage bed kept pure, for God will judge the adulterer and all the sexually immoral. 5 Keep your lives free from the love of money and be content with what you have, because God has said, “Never will I leave you never will I forsake you.” 6 So we say with confidence, “The Lord is my helper; I will not be afraid. What can mere mortals do to me?” 7 Remember your leaders, who spoke the word of God to you. Consider the outcome of their way of life and imitate their faith. 8 Jesus Christ is the same yesterday and today and forever. — Hebrews 13:4-8 NIV
sexual sins
Without Spot or Blemish
14 By his power God raised the Lord from the dead, and he will raise us also. 15 Do you not know that your bodies are members of Christ himself? Shall I then take the members of Christ and unite them with a prostitute? Never! 16 Do you not know that he who unites himself with a prostitute is one with her in body? For it is said, “The two will become one flesh.” 17 But whoever is united with the Lord is one with him in spirit. 18 Flee from sexual immorality. All other sins a person commits are outside the body, but whoever sins sexually, sins against their own body. 19 Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; 20 you were bought at a price.Therefore honor God with your bodies.—1 Cor. 6:14-20 NIV
26 That he might sanctify and cleanse it with the washing of water by the word, 27 That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish.—Eph. 5:26,27 NIV
