Isaiah 55:6

Seek ye the Lord. Here was where Israel had failed, and the reason for her exile — she had not sought to know or to obey the will of God (see ch. 6:9-12). Again and again God had invited Israel to seek Him (see Deut. 4:29; Ps. 105:4-6; Jer. 29:13, 14; etc.). Throughout the ages God has extended similar exhortations to His church (2 Cor. 6:2; Rev. 22:17).

While he is near. God was in a special sense “near” to His people Israel (Deut. 4:7; Ps. 148:14), but He is also “near” to all who call upon Him (Ps. 46:1; 145:18). The time comes, however, when stubborn rejection of the pleadings of God’s Spirit closes the door of mercy and drives the divine presence away (Isa. 1:15; Hosea 5:6; Matt. 25:10-12; cf. John 7:34; 8:21).
