Will Christians be judged for their sins?
This is an issue that many believers wonder about. I think the answer will be freeing for you as well as inspiring you to serve the Lord with zeal. The Bible refers to two different judgments; one for believers and another for unbelievers.
Revelation records the final judgment for those who do not trust Jesus for salvation.
And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away… And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works. And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works. And death and hell were cast into the lake of fire. This is the second death. And whosoever was not found written in the book of life was cast into the lake of fire. (Revelation 20:10-20) This is know as the Great White Throne Judgment.
Believers will be judged at a different time. This day of reckoning is known as the Judgment Seat of Christ. Scripture makes a crucial distinction between these two events:
For other foundation can no man lay than that is laid, which is Jesus Christ. Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble; Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is. If any man's work abide which he hath built thereupon, he shall receive a reward. If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire. (1 Corinthians 3:11-15)
Note that this occasion is a reference to building upon the foundation of Jesus Christ in your life. The things that you do for Jesus and have eternal value will be ascribed to your account, like gold, silver and precious jewels. The things you do that only matter in this life will burn up, in the renovation of this world, like wood, hay and stubble (Revelation 21 & 22).
So the answer to your question is no. We will be judged for our works after salvation, not our sins. Our sins are washed away because we have received Jesus as Savior. Hebrews 10:12 records, he offered one sacrifice for sins forever. No record of our sin remains (Hebrews 8:12; Micah 7:19). He took our sin upon Himself and defeated it with His sacrificial death and glorious resurrection. The judgment seat of Christ is not a judgment as to whether we are saved or lost, it is to determine our reward in heaven.
