It’s true that some people are self-satisfied and insensitive about the sin in their lives. Such persons may misuse the doctrine of eternal security to justify a false sense of security. On the other hand, there are those who are oppressed by an overly active conscience, sincerely wondering whether sin in their lives reveals a lack of saving faith. These persons can be rightly comforted knowing that salvation depends entirely on our acceptance of what Christ has done for us, rather than on what we have done for him.
Many Bible passages underline the reality of our security as believers in Jesus Christ: John 10:28-30; Romans 8:29-39; 1 Corinthians 3:15; Ephesians 1:13; Ephesians 4:20; Jude 24.There must be a reason.
The doctrine of eternal security is taught in Scripture, but it should only comfort true Christians who are earnestly concerned with living faithfully for Jesus Christ. Professing Christians living sinfully without remorse shouldn’t assume that their profession of faith guarantees their salvation. Banking on a past “decision” can be dangerous. They need to be reminded that if their present lifestyle is out of keeping with their profession, they are either not true children of God or are living in a manner inconsistent with who they are and with what God has done for them. If they are genuinely saved and continue in sin, God will bring corrective influences into their lives (Proverbs 3:12; Hebrews 12:6; Revelation 3:19).
Professing Christians need to seriously consider the consequences of living in a manner that is inconsistent with their commitment. Even if they believe in eternal security, their continuing sin could be an indication that they never were truly converted. If they are children of God, continuing to sin will result in correction that according to the Scriptures can result in either physical death or a painful condition designed to lovingly bring them to their senses (Psalm 89:31-32; 1 Corinthians 11:29-30; Hebrews 12:5-11).
