"If I profess with the loudest voice and clearest exposition every portion of the truth of God except precisely that little point which the world and the devil are at that moment attacking, I am not confessing Christ, however boldly I may be professing Christ. Where the battle rages, there the loyalty of the soldier is proved, and to be steady on all the battlefield besides is mere flight and disgrace if he flinches at that point." -Martin Luther (emphasis added)
Profession versus Confession
Profession: to claim openly but often falsely that one has (a quality or feeling)*
Confession: to admit that one has committed a crime or is at fault in some way*
Huge Implications - to profess your sins IS NOT to confess your sins - to profess that "Jesus is Lord, and I am a sinner" comes with an "often false" perception of my condition, i.e., "Jesus is Lord, and I am sinner... but my sins aren't that bad."
However, to confess that "Jesus is Lord, and I am a sinner" is to admit that I am 100% guilty, 100% at fault for my sins, 100% going straight to Hell, 100% deserving of that punishment, and 100% hopeless and incapable to save myself unless someone who is big and powerful and perfect and merciful intervenes on my behalf - the person of Jesus Christ (Son of God - born of a virgin, even.) To confess is to say, "Jesus is Lord, and I am wretched. Yet, through HIS grace, I am saved."
As Kennon Vaughn said this past Sunday at Fellowship Memphis, "All I did in my salvation is sin. Jesus did the rest."
