How do we know God provides for our perfection?

God mandates perfection from His people, but He also provides the means for that perfection through the sacrifice of Christ. Hebrews 10:14 states, 'For by one offering he hath perfected forever them that are sanctified.' This signifies that through faith in Christ, believers are made perfect in the sight of God, being justified and receiving His righteousness. Therefore, God's command for us to be perfect is accompanied by His provision through the redemptive work of Christ, affirming that we cannot achieve perfection through our efforts alone.
