The Berean - John 15:13-15 NASB
(13) "Greater love has no one than this, that one lay down his life for his friends. (14) "You are My friends if you do what I command you. (15) "No longer do I call you slaves, for the slave does not know what his master is doing; but I have called you friends, for all things that I have heard from My Father I have made known to you.
New American Standard Bible
John 15:13-15 presents us with an interesting and exciting expansion of our place within our relationship with Christ. Redemption, at first glance, elevates us from being a slave of unrighteousness and Satan to being a slave of righteousness and Jesus Christ. Yet, here Christ elevates our calling to an almost unimaginable height—intimate friendship with Him and the Father.
In many cases, our understanding and therefore our appreciation of this falls short of what it should be. Few or none of us have known either the depths of actual, physical slavery to another individual or the heights of walking the halls of power. In ancient Rome, the friends of the Caesar had greater access to him than his governmental counselors and military advisors. History says they had access to him at all times, even into his bedchambers.
A slave would never know such a relationship. A slave never receives a reason for the work assigned him; he simply must do it because he has no other choice. However, a friend of Christ is a confidant of the One in power, who shares the knowledge of His purpose with him. Then the friend voluntarily adopts it as his own, perhaps for no other reason than the basis of their friendship.
We do not follow Christ simply because of some chance impulse. We have been specifically chosen, summoned by Him to be His friend! Here is our obligation set boldly and clearly before us: "You did not choose Me, but I chose you and appointed you that you should go and bear fruit, and that your fruit should remain, that whatever you ask the Father in My name He may give it you" (John 15:16). We have been specifically appointed, ordained, placed in this unique relationship that we may produce the right things in life.
At first, our obligation rests upon the fact of Jesus giving Himself as the price of our spiritual redemption from slavery and death. If we have any sense at all—any discernment of what He has rescued us from and what He has given us the opportunity to possess—our sense of gratitude should explode in zeal and motivate us to loyalty because we owe Him so much!
Our sense of obligation is further built and strengthened by the knowledge that we have been specifically summoned and appointed to share in an intimate, loving, family relationship and friendship that He sustains through His office as High Priest. If we have any sense of gratitude for His work in intervening, leading, guiding, correcting, and perfecting our character so that we produce much fruit and love one another, our sense of obligation will be further stirred to ensure that we do not let Him down in any area of life. We will always strive to glorify Him.
This motivational factor is largely dependent upon feeling—but not the sickeningly sweet sentimentality of some of this world's Christianity. This feeling is derived from a clear understanding of what has been done and continues to be done in our behalf. This deep, heartfelt, and comprehending feeling arises in the minds of people who have had firsthand experience with the suffering that sin and death bring. They know in their heart of hearts that they are guilty of rebellion against this wonderful Personality who created us, died for us, and continues to be our friend through thick and thin. They know He greatly desires that friendship to continue for all eternity because He is changing us to be like Him and be one with Him.
