Ephesians 5:31-32 - For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh. This is a great mystery: but I speak concerning Christ and the church.
Faithfulness to God is important to have a good relationship as with any relationship. Now we know that if a woman being married gives her body in service to another other than her husband. She has become an adulterer.
Likewise, we being the bride of Christ and his righteousness. If we give our bodies in service to sin and wickedness, we also become adulterers...
Strive against sin...
John 8:34 - Jesus answered them, Verily, verily, I say unto you, Whosoever committeth sin is the servant of sin.
Romans 6:18 - Being then made free from sin, ye became the servants of righteousness.
Be dead to sin, but alive to righteousness in word and deed...
1 John 3:7 - Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
Let us follow Christ and live righteously, being faithful to our Husband and not like Isreal who God called a harlot for being unfaithful to Him and His commandments...
