1) Do not be unequally yoked.
This is what 2 Corinthians 6:14 says emphatically.
It is not right to enter into relationships with unbelivers. Light cannot abide with darkness. If you are dating someone who is not converted, you are playing with your life and your future.
2) Put obedience over passion.
We need to listen to the still, small voice everytime. It is not everything we do that is right. Even the Bible says that the ways that seemeth right to man, the end is destruction.
It is crucial we submit our will to the obedience to God and not obey our feelings or what society thinks.
3) Examine your personal motives.
Ask yourself genuinely: why am I in this relationship? What is my motivation?
Ego gratification? Power? Control? Selfishness or genuine affection?
As a God-fearing individual, our motives must be clean and clear.
4) Be guided by love versus lust.
It has to be about love. Love is the fruit of the Spirit. When once love is present, everything else follows.
We are advised in the Bible not to operate in lust.
5) Allow the Holy Spirit to direct and lead you.
If you feel convicted of certain behaviors, stop doing them.
