Christ says whoever confesses Him before others, He will also confess before His Father in Heaven (Mt 10:32); and whoever denies Him before others, He will also deny before His Father. (Mt 10:33) We either belong to both God the Father and the Son, or to neither; we cannot have one without the other. (Jn 17:10)
The word confess is from the Greek homologeo, meaning to speak the same thing, to be in agreement. Christ claims as His own those who agree with what He did and said, who are willing to stand with Him against the world; He’s ashamed of (Mk 8:38) and disowns everyone else. (Mt 7:23) Our eternal welfare hinges on what we think of Christ: there’s no middle ground.
Confessing Christ, agreeing with Him, is thus to find Christ, to belong to Him and obey Him. To know Him is to love Him supremely, to cling to Him above all else (Mt 13:45-46), to esteem Him exceedingly precious (1Pe 2:7), and to agree with Him that this world’s system is evil. (Jn 7:7) This implies a willingness to give up everything for Him. (Lk 14:33) We cannot have Christ and hold on to the world: He doesn’t give us this option. (Mt 10:39)
It’s a lie that we can be safe in God while loving this world (1Jn 2:15); to have Him we must let go of the world (Mk 10:21-22), we must be willing to count all things but loss for Christ. (Php 3:8) If we’re still focused on this life, if the temporal is our constant preoccupation rather than the eternal, if we’re denying His name as a manner of life for earthly benefits, then we haven’t found Him yet (Lk 14:26); we’re still His enemies, headed for destruction (Php 3:18-19), accursed. (1Co 16:22)
The world so hates Christ and His way (Jn 15:18) it moves them to despise those who know Him. (1Co 4:10) But my question to the world is this: What do you have that’s better than Christ? What fault do you find in Him? (Jn 18:38) Based on what standard? Don’t you mock because you’ve no rational defense for your hatred?
Though God’s given us all assurance in the historical fact of Christ’s Resurrection, the world blindly rejects its only treasure, the only One Who can satisfy our longing for perfection, beauty, significance, and purpose. (Col 2:3) Apart from Christ, the world has nothing worth having; of this I’m absolutely certain.
Being friends with the world makes us God’s enemy (Ja 4:4); yet from that darkness we can’t help it find the light. When knowing God is the most important thing to us, when we’re crying after knowledge, then we’ll find Him (Je 29:13) and be able to help others do so. (Ac 26:18) He rewards all who diligently seek Him. (He 11:6)
What does it mean to forfeit all?
To count all things but loss, as dung, for the excellency of knowing Him. “Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ.” (Php 3:8)
A relevant text here: “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: whose end is destruction, whose God is their belly, and whose glory is in their shame, who mind earthly things.” (Php 3:18-19)
Another: “Jesus said unto them, If God were your Father, ye would love me: for I proceeded forth and came from God; neither came I of myself, but he sent me.” (John 8:42)
