Tom asked a question on another post, and I gave a lengthy answer which I want to repeat as a stand-alone post, because I think it is important.
Here’s what I said:
Sorry to take so long to respond. I wanted to make sure I got it right, and I am just taking some extra time to look up the verses that keep going through my mind.
First, I should be clear – being prepared for the day and the hour means being a true Christian. Salvation does not depend on anything other than faith in Jesus Christ’s atonement for my sin by His death on the cross and His resurrection from the dead.
That said, James called it when he said, “So also faith by itself, if it does not have works, is dead. But someone will say, ‘You have faith and I have works.’ Show me your faith apart from your works, and I will show you my faith by my works.” (James 2:17-18 ESV)
Jesus said, “If you love me, you will keep my commandments.” (John 14:15) and “You shall love the Lord your God with all your heart…This is the great and first commandment. And a second is like it: You shall love your neighbor as yourself.” (Matthew 22:37-39)
He also said, “So, if you are offering your gift at the altar and there remember that your brother has something against you, leave your gift there before the altar and go. First be reconciled to your brother, and then come and offer your gift.” (Matthew 5:23-24, emphasis mine)
So, that last verse is a command, and it involves loving God (worship) and loving your neighbor. According to Jesus’ words, if you truly love Him (and by extension God), you will reconcile with others so that your worship of God will not be hindered.
John said, “If anyone says, ‘I love God,’ and hates his brother, he is a liar; for he who does not love his brother whom he has seen cannot love God whom he has not seen.” (1 John 4:20, emphasis mine).
Scripture is clear. If we profess to be Christians, and thus profess that we love God, we must live that out by doing everything humanly possible to be reconciled with others (specifically, per the use of the term “brother”, other Christians – though we are also commanded to love our enemies as well).
So, husbands, so, wives, so, brothers and sisters in Christ – fervently, doggedly pursue reconciliation as proof of your profession of faith.
As Paul says in Romans, “If possible, so far as it depends on you, live peaceably with all.” (That is where I don’t want anyone to make an excuse, and say, “I tried to reconcile, but he/she wouldn’t…” unless you have really, truly, before God and man, made every possible attempt to reconcile).
