The Bible also teaches that our reward will be given according to our works.
Matthew 10:42, "And whoever gives one of these little ones only a cup of cold water in the name of a disciple, assuredly, I say to you, he shall by no means lose his reward.”
Luke 6:35, "But love your enemies, do good, and lend, hoping for nothing in return; and your reward will be great, and you will be sons of the Most High. For He is kind to the unthankful and evil."
1 Corinthians 3:13-14, "each one’s work will become clear; for the Day will declare it, because it will be revealed by fire; and the fire will test each one’s work, of what sort it is. If anyone’s work which he has built on it endures, he will receive a reward."
Colossians 3:23-24, "And whatever you do, do it heartily, as to the Lord and not to men, knowing that from the Lord you will receive the reward of the inheritance; for you serve the Lord Christ."
2 John 1:8, "Look to yourselves, that we do not lose those things we worked for, but that we may receive a full reward."
Revelation 2:10, "Do not fear any of those things which you are about to suffer. Indeed, the devil is about to throw some of you into prison, that you may be tested, and you will have tribulation ten days. Be faithful until death, and I will give you the crown of life."
Revelation 3:11, "Behold, I am coming quickly! Hold fast what you have, that no one may take your crown."
Revelation 22:11-12, "He who is unjust, let him be unjust still; he who is filthy, let him be filthy still; he who is righteous, let him be righteous still; he who is holy, let him be holy still.” “And behold, I am coming quickly, and My reward is with Me, to give to every one according to his work."
