The pure in heart.We purify the heart by daily confession of our sins (1 John 1:9), and by seeking the cleansing power of God’s Word (Eph. 5:26). The Spirit of God uses the Word of God to sanctify (purify) the believer from the inside out (John 17:17; 1 Thess. 4:3a; 5:23). This process of inner purification will continue throughout the life of the believer (Prov. 4:18; 2 Pet. 3:18).
