If I have a life of rich study in the Word (my tendency) but less in the arena of prayer, I have a dry spiritual life.

If I have a life rich in prayer but less in the study of the Word, I have a weak spiritual life.

The spirit and truth were always means to walk together (Jn 4:23,24,14:17,15:26;16:13; Acts 28:25; Rom 9:1; Eph 1:13; 2 Thess 2:13; 1 John 4:6; 5:6).
