Pursue peace with all people, and holiness, without which no one will see the Lord. Heb 12:14
Without holiness, no one will see the Lord does not only mean see Him on that Day, which it does mean. But, it also means we won't see Him clearly in our lives, our ministries.
Holiness-hagiasmos, really means sanctification or being set apart. Being holy means we have set the Lord apart from everything else and ourselves apart to Him from everything else. When there is anything that we hold above or even on an equal status to Him, our affections, our attentions are divided. What that does is brings a shadow of how we see the Lord. We can't see Him as He is because something distorts him, a shadow of our uncrucified self-life projects itself on Him.
He now is misrepresented to us and we misrepresented Him to others in our lives and ministries.
"Sanctify yourselves, therefore, and be ye holy: for I am the LORD your God." Lev. 20:7 "Because it is written, Be ye holy; for I am holy." I Pet. 1:16
"This is the message which we have heard from Him and declare to you, that God is light and in Him is no darkness at all." I John 1:5
"Every good gift and every perfect gift is from above, and comes down from the Father of lights, with whom there is no variation or shadow of turning." James 1:17
God is calling us to be perfect by walking before Him in all the Light we have been given. We don't have all Light and perfection to Him is to be faithful to all the Light we have. When He gives more light then we are required to walk in that light, that He considers perfection. Any unfaithfulness to the Light given produces darkness, a shadow, if not corrected, how great that darkness becomes.
If we are to have revival, it will be because we will begin to return ourselves to the Light, and take responsibility to all sin against it. We cast ourselves on his mercy and grace in humility and brokenness, and He will draw nigh.
We cannot rectify many of the things damaged, caused by our disobedience to the Light, but we must do what he says in regards to that, and leave the rest to Him.
Remember one of the great benefits of walking in the Light(we imperfect light), as He is in the Light( He perfect or all Light). When we confess our sins, He is faithful and just to forgive us of our sins...and, cleanse us(from disobedience) AND, from all the unrighteousness we have not been given Light on. There is NO condemnation, for areas of unilluminated unrighteousness. Selah!!
