Why is understanding grace versus works important for Christians?

Understanding the distinction between grace and works is vital for Christians as it impacts their assurance of salvation and their relationship with God. The Bible teaches that any form of legalism—believing that one can earn favor with God through personal obedience—is not only erroneous but also spiritually dangerous. Galatians 5:1-4 warns that those who seek justification through the law disconnect themselves from the grace of Christ, thus condemning themselves. This underscores the importance of grasping that sanctification, like justification, is an unconditional work of grace performed by God. Misapprehending this truth can lead to a burdened faith, self-righteousness, and a misunderstanding of God's liberating grace.
