So how do we walk as Jesus walked and what does be ye holy as I am holy mean?
Consider it true that we are now dead to sin and alive to God.
Consider it true that we are reconciled to God through Christ, having nothing to do with our own works whether good or bad, but in Christ alone.
Consider it true that being reconciled in Christ, our reconciliation never changes because He never changes.
Consider it true that you now live personally in God's presence, that He always loves you, and always accepts you, and is always fully committed towards what is good for you. For He has promised, I will never leave you, nor forsake you.
These things describe for me the faith in Christ that results in walking in His Spirit.
Be holy as I am holy, "holy" is "set apart". When God makes someone holy, He is setting them apart for some particular purpose. I think an understanding of this can be seen in,
Ephesians 4:22-25 KJV
22) That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;
23) And be renewed in the spirit of your mind;
24) And that ye put on the new man, which after God is created
in righteousness and true holiness.
25) Wherefore putting away lying,
speak every man truth with his neighbour: for
we are members one of another.
In this passage, we put off lying, to speak truth. We stop unrighteousness, and do righteousness. The doing of what is right. The person who does what it right, righteous. For we are members one of another. We've been born into the body of Christ, and now we are set apart for the same as was Christ, the sacrificing of ourselves for others.
I welcome anyone's thoughts regarding holiness, I've pondered this myself for a long time. I think when we say God is holy - set apart - this is to say that He never violates His Own nature, He always remains true to Himself, Who He is.
This is the beauty of His Holiness, this wonderful reality about our God. That He is always the loving and kind and all powerful transcendant Being Who has revealed Himself to us in Jesus Christ.
Jesus came to offer Himself to serve others, we are to do the same, and this separation for that purpose is our holiness. If we are serving others out of our faith in Christ, then we are not doing works of flesh, we are busy doing works of faith, as pre-ordained by God, whichever they should be.
Much love!
