Matthew 5:8 (Study notes of Dr. Constable~Soniclight.com)

Matthew 5:8

(New International Version)
Blessed are the pure in heart, for they will see God.

(New American Standard Bible)
Blessed are the pure in heart, for they shall see God.

The "pure in heart" are those who are single-minded in their devotion to God and therefore morally pure inwardly. Inner moral purity is an important theme in Matthew and in the Old Testament (cf. Deut. 10:16; 30:6; 1Sam. 15:22; Ps 24:3-4; 51:6, 10; Isa. 1:10-17; Jer. 4:4; 7:3-7; 9:25-26). Likewise freedom from hypocrisy is also prominent (cf. Ps 24:4; 51:4-17; Prov. 22:11; Matt. 6:22,33).
Jesus probably implied both ideas here.

The pure in heart can look forward to seeing God in the person of Messiah when He reigns on the earth (Ps. 24:3-4, Isa. 33:17, 35:2; 40:5). Messiah would be single-minded in His devotion to God and morally pure. Then there will be a correspondence and fellowship between the King and those of His subjects who share His character. No one has seen God in His pure essence without some type of filter. The body of Jesus was such a filter. Seeing God is a synonym of having intimate knowledge of and acquaintance with Him (John 14:1, John 1:1-4).
