It does show those who PROFESS to KNOW GOD but by their DEEDS they deny Him. We are to pick up our cross (deny ourselves) and FOLLOW HIM. Many LIVE as ememies of he cross. Its not in word only the denial of Him occurs. Its being ashamed of his words in the DOING of them. He asks, "why do you say Lord Lord and not do what I say?" Its ones disobedience to HIM, the gospel (His words).
Who hath BELIEVED the report? but they have not all OBEYED theres the stumbling at the word. Being disobedient to Him.
2Thes 1:8 In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ:
1Peter 4:17 For the time is come that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God?
The "house of God" is ~synonomous~ with those who ~obey~ the gospel as opposed with those who obey not the gospel. Yet our obedience is fulfulled 2Cr 10:6 As we are to come to the "obedience" of the faith Rom 16:26
2Titus 2:19 Nevertheless the foundation of God standeth sure, having ~this seal~, The Lord knoweth them that are his. And, Let ~every one~ that nameth the name of Christ ~depart from~ iniquity.
If not He says...
Mat 7:23 And then will I profess ~unto them~, I never knew you: ~depart~ from me, ye that work iniquity.
Phil 3:17 Brethren, be followers together of me, and ~mark them~ which ~WALK~ SO as ye have ~us~ for ~an ensample~.
Its their WALK, the FOLLOWING IN ~THE WAY~ IN DEED and IN TRUTH (not SAYERS but DOERS) as persecution comes to those who seek to LIVE GODLY (not OTHERWISE) in Christ.
Phil 3:18 (For many ~WALK~, of whom I have told you often, and now tell you even weeping, that they are ~the enemies~ of the cross of Christ:
Phil 3:19 Whose end is destruction, whose God is their belly, and whose glory is in their shame, who mind earthly things.)
