Psam 63:1 O God, thou art my God; early will I seek thee: my soul thirsteth for thee, my flesh longeth for thee in a dry and thirsty land, where no water is;
Psa 63:2 To see thy power and thy glory, so as I have seen thee in the sanctuary.
Psa 63:3 Because thy lovingkindness is better than life, my lips shall praise thee.
Paul the Apostle captured this same hunger in the New Testament perspective and cried
Php 3:10 That I may know him, and the power of his resurrection, and the fellowship of his sufferings, being made conformable unto his death;
The inbuilt hunger for God can not be satisfied with anything else. Only God can satisfy that hunger.
