Why is self-separation and consecration not enough for Christians?

Self-separation and consecration are commendable efforts for Christians, representing one's intention to live a life dedicated to God. However, the text underscores that these actions alone cannot obtain the favor or merit of God. Even our best works are tainted by sin and thus require the cleansing power of Christ's sacrifice. True devotion must recognize its limitations and instead anchor its hope in Christ, acknowledging that while we strive to honor God, we are still in need of His grace to be truly accepted. Our works, no matter how dedicated, must be submitted beneath the perfect sacrifice of Jesus.
