Not only does The Bible teach that grace and security are not a permit to sin, but Christians should keep in mind that we all face a judgment one day. Understand clearly that a truly saved person will never face judgment for their sins; the issue of Heaven and Hell is decided only in this life. Believers will, however, be judged at some point in time for how they lived their lives for Jesus Christ while they were alive. The ultimate goal of every believer at the Judgment should be to hear the same words the good steward heard in the Parable of the Talents which Jesus told, “Well done, good and faithful servant.”
Let’s take a look at this judgment believers face. We learn in Romans 14:10-12 as Paul wrote to the Roman believers, that we will all stand at the Judgment Seat of Christ and account for how we lived our lives for him. Since we aren’t going to be judged for our sins what then is the purpose of this judgment? The judgment believers face is to determine the rewards we will receive for the things we have done for Jesus while living. One of the best descriptions of what will happen can be found in 1 Corinthians 3:10-17
What we receive are crowns for various services we have rendered on behalf of Jesus Christ during our lives. Descriptions of these can be found in several places in Scripture: 2 Timothy 2:5, 2 Timothy 4:8, James 1:12, 1 Peter 5:4, and Revelation 2:10.
