"Do not be deceived, God is not mocked; for whatever a man sows, this he will also reap" (Gal 6:7). God has built a cause-and-effect into life which automatically judges. "'Vengeance is Mine, and retribution, in due time their foot will slip; for the day of their calamity is near'" (Dt 32:35). "'I will repay', says the Lord" (Ro 12:19). "God is not one to show partiality" (Ac 10:34). There is "no injustice with God" (Ro 9:14). He is "the one who impartially judges according to each one's work" (1Pe 1:17). "We know that the judgment of God rightly falls upon those who practice such things" (Ro 2:2). "How unsearchable are His judgments" (Rev 15:3). "'Righteous and true are your ways'" (:3).
What you do makes a difference because it determines whether you will "inherit the kingdom" (Mt 25:34). What qualifies is if you help feed, clothe and house people, and visit people when they are sick or in prison (:35-36). They "were judged from the things which were written in the books, according to their deeds" (Rev 20:12). It should make one take notice that his actions are actually recorded. "Whatever good thing each one does, he will receive back from the Lord" (Eph 6:8). "You recompense a man according to his work" (Ps 62:12). Paul quotes this regarding "the day of wrath and revelation of the righteousness judgment of God, who WILL RENDER TO EACH PERSON ACCORDING TO HIS DEEDS" (Ro 2:5-6). Jesus says "'My reward is with Me, to render to every man according to what he has done'" (Rev 22:12). "By perseverance in doing good . . . [you receive] eternal life" (Ro 2:7). "This is the promise which He Himself made to us: eternal life" (1Jn 2:25). "'This is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent'" (Jn 17:3). "'For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life'" (3:16). But "He who does not have the Son of God does not have the life" (1Jn 5:12).
God is "the Judge of all" (Heb 12:23) but "not even the Father judges anyone, but He has given all judgment to the Son" (Jn 5:22). He is "the One who has been appointed by God a Judge of the living and the dead" (Ac 10:42). "God will judge the secrets of men through Christ Jesus" (Ro 2:16). "There is nothing covered up that will not be revealed, and hidden that will not be known" (Lk 12:2). Is there a time for this? "We will all stand before the judgment seat of God" (Ro 14:10). "He has fixed a day in which He will judge the world in righteousness through a Man whom He has appointed, having furnished proof to all men by raising Him from the dead" (Ac 17:31). "Having overlooked the times of ignorance, God is now declaring to men that all people everywhere should repent" (:30). He "is patient toward you, not wishing for any to perish but for all to come to repentance" (2Pe 3:9). "He ordered [the Apostles] to preach to the people and solemnly to testify" (Ac 10:42) about it. "The Lord Jesus will be revealed from heaven . . . dealing out retribution to those who do not know God and to those who do not obey the gospel of our Lord Jesus" (2Th 1:7-8). "'Do not fear those who kill the body but are unable to kill the soul; but rather fear Him who is able to destroy both soul and body in hell'" (Mt 10:28). "The wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord" (Ro 6:23). "'My sheep hear My voice, and I know them, and they follow Me; and I give eternal life to them, and they will never perish'" (Jn 10:27-28). "'In My Father's house are many dwelling places; if it were not so, I would have told you; for I go to prepare a place for you'" (Jn 14:2). However, "'He will also say to those on His left, 'Depart from Me, accursed ones, into eternal fire which has been prepared for the devil and his angels''" (Mt 25:41).
