The person that you are most likely to be in contention with at any given time is the one that you spend the most time around, while at the same time, is the one that you are most generally going to be in agreement with, the one that you trust the most, will be the one that you spend the most time around. “And they twain shall be one flesh: so then they are no more twain, but one flesh.” (Mark 10:8)
It is quite easy to interpret this verse if we consider it in the Spiritual realm, they will not inhabit the same body, the husband and wife will not have the same taste in food or entertainment, but they will be completely in agreement about the truths of the Word of God, there will be no discrepancies as to how they view the Lord God.
The man Paul, who name was once Saul in the Scriptures was a feared man by many, even after his meeting with the Lord on the road to Damascus, feared by those at first that had been shown the truths of the Word of God that Jesus Christ is indeed the anointed of the Lord, the Messiah, and then feared, and hated by those who once held complete power over the people with their religious ideologies and traditions. It was not until Paul went and spoke to many that he was then accepted as one sent by God for the glory of God. Those that hated him now loved him, and those who had once called him one of their own now despised him.
Most people are very concerned about first impressions when they meet someone, most generally there is a category that they attempt to fit into, and almost always for the sake of self, they may not always want to be liked, but they do want to be accepted. The man of God only alters who he is as he is shown further revelations of the truth from the Holy Spirit, and that can only occur by diligently studying the Word of God and praying fervently for the Lord to reveal those truths to him. Once he is sure of these truths, no one can altar his demeanor, he will be who he is being made into, he will not deviate from the truths shown to him.
Many of those he has known will forsake him, he is being transformed by the Lord (Romans 12:2) he is being made into the image of Christ. (Romans 8:29) “For the which cause I also suffer these things: nevertheless I am not ashamed: for I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day.” (2 Timothy 1:12)
I suggest, because of human nature, that many of Paul’s friends tried diligently to sway him back, that the debates were intensive, concerned many Scripture verses, much of the traditions of what he had been taught and had adhered to in his life up to that point on that road when the Lord revealed Himself to him were discussed, and I am quite sure that at times in his early walk with Christ he doubted. He knew for a fact that before that day he served God, Jesus just needed to reveal one truth to him, that He is God. Not a man sent by God, not a prophet of renown and great power from the Lord, but God Himself.
When we meet Jesus, we are not meeting our best friend, we are encountering the Creator and Sustainer of all that exists, we are in the presence of the Most High, the Almighty, and we are incapable from that point on to reverence Him as anything less than that. If those we have called friends and family up to that point in our lives cannot accept that, so be it, if the world begins to hate us, so be it. No one the Lord has called to Himself, no one that has been chosen by God to become a permanent part of His family will ever turn from Him, nor will they be allowed to.
He will be the One that you will be in the greatest contentions with, “For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.” (Gal. 5:17) And He will be the One that the entirety of your life will revolve around “We love him, because he first loved us.” (1 John 4:19) If He is not everything to you, then you must question who it is you are serving.
