That you may be sons of your Father … therefore you shall be perfect.We only become
sons of God through faith in Jesus Christ (Rom. 8:14-15; Gal. 4:4-7; 1 John 3:1). We are only
perfect when we are clothed with the righteousness of Christ. The word
perfect is also used in the New Testament for maturity or spiritual completeness (2 Cor. 13:11; Phil. 3:12-15; Col. 4:12; James 1:4; 1 Pet. 5:10).
