If anything is certain about the future, there is a judgment according to works for all who live and die. How can anyone who says he believes the Bible claim that works are not required of the Christian when God emphatically declares that they are required of us, even though they do not justify us before Him?
The truth is plain. If a Christian does not work, there will be nothing for God to judge and thus no evidence the person is prepared to inherit His Kingdom. God will not give him salvation because there will be nothing to verify that he belongs there. The lack of evidence proves that he does not belong there! Such a one is not a son of God. A faith that does not work is dead (James 2:17, 20, 26). God is the God of the living, and according to James 2:22, faith is perfected, brought to completion, by works. Sanctification is necessary as a witness to the Christian's character as he passes before the judgment seat of Christ.
Do we not all desire to inherit the Kingdom of God? Certainly, we must if we are at all impressed with the glory to which God has called us. However, have we considered deeply whether we would enjoy being there, should we be given that privilege? God's Kingdom will be a holy place inhabited by holy people. Is it not apparent that those who inherit God's Kingdom will have spent a great deal of time being prepared, trained, and formed and shaped for living there?
The concept of deathbed repentance and absolution is a lie palmed off by Satan. Likewise false is the belief in a purgatory following death, in which a person prepares for living in paradise. These are nowhere found in Scripture, nor is the idea that one needs only to be justified through Christ's blood. If these things were so, Romans 5:9-10 would not declare:
Much more then, having now been justified by His blood, we shall be saved from wrath through Him. For if when we were enemies we were reconciled to God through the death of His Son, much more, having been reconciled, we shall be saved by His life.
The false concepts above do not take into consideration that God's purpose includes more than just atoning for our sins through Christ's blood. God's purpose includes the work of Jesus Christ as our High Priest, perfecting our character by means of living in us through His Spirit (John 14:18-23). It is our High Priest, Jesus, who intercedes in our behalf (Romans 8:26-27). As Head of the church, He inspires and corrects us, and He gives us gifts to fulfill our responsibilities (Ephesians 4:7). He labors to create in us a clean heart, purified and in the character image of the Father (II Corinthians 3:17-18).
We need to be sanctified as well as justified. Sanctification requires the works of submission to and cooperation with Almighty God to bring to completion His purpose for us. King David writes in Psalm 16:11, "You will show me the path of life; in Your presence is fullness of joy; at Your right hand are pleasures evermore" - a brief snapshot of what life will be like in the Kingdom of God. No one can be happy where he is not in his element. An unsanctified person would not find God's Kingdom congenial to his tastes and character. Being there would be a condemnation rather than a blessing.
