If there ever was someone who deserved the distinction of being absolute, that someone is Jesus. He declared himself the absolute, only way to enter into the kingdom of heaven (John 14:6). In this question, there is no grey area - not a single drop of ying yang to dilute what He has spelled out explicitly in His word. Christ is salvation for those who believe, but salvation is bigger than we think. It is not just a salvation from judgment. Christ's salvation is also salvation into righteousness. In the same moment that He freed us from the bloody (literal) cycle of sacrifices, He freed us into obedience by way of His righteousness. We are no longer ruled by the destruction of our secret hearts and the destruction of our sinful humanity. We are not ruled by the darkness that seems to rule the world.
"For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God." (2 Corinthians 5:21)
We are freed from judgment by Christ's atoning sacrifice and freed into obedience by Christ's imputing righteousness.
What we believe about Jesus Christ matters because our lives could never stand up to God's righteous judgment. My sin goes before me and follows close behind. The good I want to do gets muddled up in my own schemes and I am daily reminded of my sin that leads to death. I am weak against greed and pride and lust and fear and faithlessness. There is not a day I could stand upright in the face of God's righteous judgment.
But God, being rich in mercy called His children before the foundations of the world into freedom from the judgment that is due our dead bones.
I need for Christ to offer a salvation that is more than just a courtroom scene where He takes my guilty sentence. I need for Him to be the justice I act and the mercy I show and the love I share. I need for Him to be the righteousness that roots out my fear and greed and lust and pride and I need Him as replacement. I need for Christ to be who God sees when I stand before the throne of judgment. AND HE IS, dear friends!
What we believe about Jesus Christ matters because His sacrifice both atones for our sin (receiving the judgment we are due) AND imputes our righteousness (replacing ours with the perfect life Christ lived).
He is the perfect heart condition when I try to muster compassion. He is the perfect generosity when I scrounge for change. He is the perfect host when I frenzy about with overlapping plans. He is the perfect listener, counselor, and encourager when I am trying very hard and very imperfectly to be all those things.
Yesterday, I sang "A Mighty Fortress is Our God" with a group of strangers in a beautiful church near Union Square. This second verse really tore apart my spirit.
Did we in our own strength confide, our striving would be losing; Were not the right Man on our side, the Man of God’s own choosing: Dost ask who that may be? Christ Jesus, it is He; Lord Sabaoth, His Name, from age to age the same, And He must win the battle.
I do a lot of striving - a lot of confiding in my own strength - and none of it gets me closer to a better salvation. Absolutely not one single attempt (or many) at righteousness will be the reason Christ invites or denies me into His kingdom. Because there is only one right Man, a Man of God's own choosing, who has the power and perfection to be condemned in my guilty place so that I can become the righteousness of God. Salvation doesn't get any better than that.
No matter how many hungry folks we feed or naked people we clothe or strangers we invite in, we would never do it perfectly and we would never do it enough. I would never do righteousness enough and (if I could be so bold) you wouldn't either. We are always striving and our striving is always losing, but God made a way for us to be free of judgment and freed to righteousness. And that way is Jesus.
What we believe about Him is the most pressing, most prominent, most permanent thing today. He makes perfect all our imperfect attempts because He gave us His righteousness. We are freed from striving for perfection and freed from losing at that game. We are freed into obedience because salvation doesn't depend on our righteous performance. Salvation depends on the cross and Christ performed that perfectly... so that we could enter into His joy and invite others to the banquet table to meet the Man of God's own choosing.
As I click at my keyboard, wet and sloppy tears are tracking through the blush on my cheeks. Everything is snot-messy because salvation will always be a mystery. I don't understand why I get to know Christ. I don't understand why my sin does not banish me forever from His presence. I don't understand why I never have a better response. I don't understand why my daily song doesn't sound like worship. I don't understand why my heart can be so resistant to miracles.
Where is the one who is wise? Where is the scribe? Where is the debater of this age? Has not God made foolish the wisdom of the world? For since, in the wisdom of God, the world did not know God through wisdom, it pleased God through the folly of what we preach to save those who believe.
For Jews demand signs and Greeks seek wisdom, but we preach Christ crucified, a stumbling block to Jews and folly to Gentiles, but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God. For the foolishness of God is wiser than men, and the weakness of God is stronger than men. For consider your calling, brothers: not many of you were wise according to worldly standards, not many were powerful, not many were of noble birth.
But God chose what is foolish in the world to shame the wise; God chose what is weak in the world to shame the strong; God chose what is low and despised in the world, even things that are not, to bring to nothing things that are, so that no human being might boast in the presence of God. And because of him you are in Christ Jesus, who became to us wisdom from God, righteousness and sanctification and redemption, so that, as it is written, “Let the one who boasts, boast in the Lord.” (1 Corinthians 1:20-31 ESV)
