What does the Bible say about erring from the truth?

The Bible, particularly in James 5:19-20, addresses the reality that believers can stray from the truth. James uses the term 'err' to highlight that even those who claim to know Christ can be led astray, often due to the influence of their old, sinful nature. This old man within us can cause rebellion against God's truth, which leads to the necessity of prayer and encouragement from fellow believers to restore those who wander. Isaiah 53:6 similarly illustrates that 'all we, like sheep, have gone astray,' confirming that this struggle is common to all. Therefore, it's crucial to acknowledge that while our sins are paid for, the battle against our flesh continues throughout our lives.
