Let’s be clear from the outset: The Roman Catholic doctrine of purgatory is taught nowhere in Scripture. It was invented to accommodate Catholicism’s denial of justification by faith alone. And it offers false hope to millions who anticipate ample time beyond the grave—perhaps eons, if necessary—to achieve their own justification.
Scripture very clearly teaches that an absolutely perfect righteousness is necessary for entry into heaven. Jesus said, “I say to you that unless your righteousness surpasses that of the scribes and Pharisees, you will not enter the kingdom of heaven” (Matthew 5:20). He then added, “Therefore you are to be perfect, as your heavenly Father is perfect” (Matthew 5:48)—thus setting the standard as high as it can possibly be set.
The Only Way to Heaven
Later in His ministry, when the rich young ruler approached Jesus to ask how he might enter heaven, Jesus upheld this same standard of absolute perfection. He began by challenging the clear implication that the young man hoped he could attain a sufficient goodness of his own to merit heaven: “Why are you asking Me about what is good? There is only One who is good” (Matthew 19:17). Notice: Jesus did not disclaim that He Himself was sinlessly perfect (a common misinterpretation of this passage). He was simply pointing out plainly that the standard of perfection required to earn heaven is impossible for fallen creatures.
Because the young man was undeterred by this, however, Jesus told him that to obtain eternal life, he must have a track record of perfect obedience to the law (Matthew 19:17-22). Again and again, Jesus made the required standard of righteousness impossibly high for all who would seek to earn God’s favor on their own.
The young ruler clearly did not understand or acknowledge his own sinfulness. He assured Jesus that he had indeed kept the law from his youth up (v. 20).
Jesus subtly pointed out the young man’s covetousness (v. 21), which was a violation of the tenth commandment. From the outset of His conversation with the young man, the Lord was prodding him to confess that no one but God Himself is truly good. But the rich young ruler was unwilling to face his own sinfulness, and so he went away without salvation.
The disciples marveled at this. The young man was evidently—from a human perspective—one of the most righteous individuals they’d encountered. Notice that no one disputed his claim that he had obeyed the law. That suggests there were no overt sins in his life that anyone could point to. He seemed the best of men. So the disciples were floored when he walked away with no assurance of eternal life from Jesus. In fact, Jesus told them, “Truly I say to you, it is hard for a rich man to enter the kingdom of heaven. Again I say to you, it is easier for a camel to go through the eye of a needle, than for a rich man to enter the kingdom of God” (Matthew 19:23-24).
There’s no mistaking Jesus’ point. He was setting the standard at an impossible height. He was saying that the most fastidious legal observance is not enough. The most flawless external righteousness is not enough. All the worldly advantages of wealth are of no help. Only absolute perfection is acceptable to God. Our Lord kept underscoring these truths because He wanted people to see the utter futility of trying to earn righteousness by any system of works.
The disciples got the message. They asked, “Then who can be saved?” (Matthew 19:25).
And Jesus replied, “With people this is impossible, but with God all things are possible” (Matthew 19:26).
Accepted By Imputation
We know from Paul’s treatise on justification in Romans 4 that God saves believers by imputing to them the merit of Christ’s perfect righteousness—by no means because of their own righteousness. God accepts believers “in Christ.” He clothes them with the perfect righteousness of Christ. He declares them perfectly righteous because of Christ. Their sins have been imputed to Christ, who has paid the full penalty. His righteousness is now imputed to them—and through His imputed righteousness—they receive His full merit. That is what justification by faith means. The Father “made Him who knew no sin to be sin on our behalf, so that we might become the righteousness of God in Him” (2 Corinthians 5:21). Continue reading
