The Bible has several verses telling us that our relationship with God is best observed by our relationship with people.
However, it even seems to go deeper than this. Your relationships with others determines God’s relationship with you.
I know this is a horrible thing to say, what with grace and everything, but alas, I didn’t say it, God who taught us grace, said it!
Here are a couple examples:
“forgive us our debts, as we forgive our debtors.”
“Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me.”
“husbands, dwell with them according to knowledge, giving honour unto the wife, as unto the weaker vessel, and as being heirs together of the grace of life; that your prayers be not hindered.”
“Blessed are the merciful: for they shall obtain mercy.”
“Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness. . . hatred, variance, emulations, wrath, strife, seditions, heresies, Envyings, murders . . . and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.“
“But if any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel.”
“But whoso hath this world’s good, and seeth his brother have need, and shutteth up his bowels of compassion from him, how dwelleth the love of God in him?“
It is much easier to assume that our relations with others has no impact on our faith, prayers, or whether we are saved or not. What is difficult is to deal with these startling truths.
What we do matters. Maybe not to you so much, but they sure seem to matter to God.
Love is the fulfilling of the Law. The Law is all the words that come out of the mouth of God. God is love. When we say we have faith in God, the Bible says that means we hear God’s Word. We do what God says, and God says what He is.
It’s all wrapped up in love.
If we do not love each other, it is impossible to prove in any real way that you love God.
“He that loveth not knoweth not God; for God is love.“
How you treat others is a big deal when it comes to faith. Let it be a big deal in your faith.
And, just to clarify, you don’t get saved by being nice to people. You get saved by faith. By faith you are crucified, buried, and raised up with Christ to newness of life. New life in Christ fulfills the law–it loves people, as Christ loved you and gave Himself for you. If there is no evidence of that new life, there should be no assurance that you are saved.
