Why is doing the will of God important for Christians?

In Matthew 7:21, Jesus states that only those who do the will of His Father will enter the kingdom of heaven. The will of God encompasses believing in Christ (John 6:29) and living out that faith through obedience. A true believer’s life will demonstrate their faith through actions that align with God's commandments, but these actions do not save them; rather, they are evidence of their faith and relationship with Jesus. This underscores that true obedience flows from a heart transformed by grace and illustrates the genuine faith that God desires.
