{Leave...Cleave...One Flesh}

Purpose: Mirror God's self-sacrificial, other centered love for eternal objectives in all potential and actualized relationships

I. Commitment to Christlikeness 

Ps 84:10 a day in Your courts is better...than dwell in the tents of wickedness. 11 For the LORD God is a sun and shield; The LORD will give grace and glory; No good thing will He withhold From those who walk uprightly
1Pt 1:15 but as He who called you is holy, you also be holy in all your conduct, 16 because it is written, "Be holy, for I am holy."

B. Don't train yourself to like something that's not good for you 1Th 5:22 Abstain from every form of evil, 1Pt 2:11 Abstain from fleshly lusts
       (3 systems: testosterone -> Eros -> dopamine -> Romantic (agape?) -> oxytocin -> Attachment (philos/stroge) -> serotonin   

C. Don't defraud 1Thess 4”1 Finally then, brethren, we urge and exhort in the Lord Jesus that you should abound more and more, just as you received from us how you ought to walk and to please God;2 for you know what commandments we gave you through the Lord Jesus. 3 For this is the will of God, your sanctification: that you should abstain from sexual immorality/fornication; 4 that each of you should know how to possess his own vessel in sanctification and honor, 5 not in passion of lust, like the Gentiles who do not know God; 6 that no one should take advantage of and defraud his brother in this matter, because the Lord is the avenger of all such, as we also forewarned you and testified. 7 For God did not call us to uncleanness, but in holiness. 8 Therefore he who rejects this does not reject man, but God, who has also given us His Holy Spirit.9 But concerning brotherly love you have no need that I should write to you...
Defraud: To take something from by fraud; Fraud: A deception deliberately practiced in order to secure unfair or unlawful gain.

Questions for Reflection/Discussion/Response:

1. Is it God's will that everyone be married (1Cor 7)? What are some advantages/disadvantages of being single or married?
2. If one is “asleep in the will of God” re: a spouse should they be sleepwalking in search of one?
3. Are platonic relationships possible? Shouldn't we be desiring the highest interest of all we meet irregardless of their mate potential?
4. If someone can't trust God to provide what's best when it's best, are they believing the Satan's oldest lie that God isn't good:
5. Have you committed yourself to holiness and trusting God to bring about His perfect will in your life? When did you do that?
