Every relationship is based or founded on something. For example, some relationships are based on the fact that both people work for the same company, attend the same school, or sharing a similar interest in a hobby or sport.

With all of relationships, once a common bond is no longer present, the relationship will tend to deteriorate. For example, once a child graduates from high school and moves off to college, he or she will probably lose most of the relationships formed with classmates, because school is no longer a common bond and thus there is nothing holding the relationship together.

However, if your relationships are formed around a common belief in Christ, then no matter what else happens in life, as long as that common bond is still present those relationships will last.

Thus, it is clear why 2 Corinthians 6:14 instructs believers not to marry unbelievers: Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness?

If you want to maintain lasting, stable relationships, they must be Christ-centered.

God's love for you is unconditional and everlasting. God loves you exactly as you are, and He loves you no matter what you do. God doesn't love you because you are a "good" person; instead, God demonstrates his own love for us in this: While we were still sinners, Christ died for us (Romans 5:8).

God is abounding in love and faithfulness (Exodus 34:6).

In 1 John 4:9-11, we are told that, because of God's love for us, we ought to love one another: This is how God showed his love among us: He sent his one and only Son into the world that we might live through him. This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins. Dear friends, since God so loved us, we also ought to love one another.

"One another" even includes those that are hard to love. Remember, God loves you even though you're not always easy to love. Therefore, you, also, ought to love others, especially those that aren't easy to love.
