You ever seen a kid who looks just like their Mom or Dad? Upon seeing them together with their parents it is clear who they belong too. The same is true of us as Christians? How so? Holiness.
Hebrews 12:14 says without holiness no one will see the Lord. When people think of “holiness” they often think of monks crammed up into tiny little cloisters and uncomfortably scratchy robes, devoting themselves to the monastic lifestyle. Is that what is really going on? I don’t think so, and I hope you don’t either.
Holiness is not an ancient archaic form of godliness where one denies all the creature comforts and worldly pleasures, holiness is nothing more than family resemblance. What do I mean? Read 1 John 3:
Everyone who practices sin also practices lawlessness; and sin is lawlessness. You know that He appeared in order to take away sins; and in Him there is no sin. No one who abides in Him sins; no one who sins has seen Him or knows Him. Little children, make sure no one deceives you; the one who practices righteousness is righteous, just as He is righteous; the one who practices sin is of the devil; for the devil has sinned from the beginning. The Son of God appeared for this purpose, to destroy the works of the devil. No one who is born of God practices sin, because His seed abides in him; and he cannot sin, because he is born of God. By this the children of God and the children of the devil are obvious: anyone who does not practice righteousness is not of God, nor the one who does not love his brother. (1 John 3:4-10)
Notice that those who sin will resemble the devil? Notice those who practice righteousness resemble their Father, God? God is holy (Isa. 6:1-4) and in His holiness He is making His family resemble Himself by creating children (1 John 3:1) who are holy as He is. Why talk of this during our 8th Mark on discipleship? Because holiness is the aim of discipleship, and without it, no one will see the Lord.
The question then comes to us: does our own life reveal sight of the Lord? Or hide Him?
