How can a young man keep his way pure? By guarding it according to your word.

Vigilance, continuous and never flagging vigilance using the Word as my armor to protect and lead me along the King's Highway with the Holy Spirit as my guide to lead and interpret each step of the Way. Hallelulah.

With my whole heart I seek you; let me not wander from your commandments!

There is so much emphasis of wholeness of effort, of singleness of purpose in this Psalm.  It is indeed that I must seek you with all my heart, soul, mind and strength.  You must be the focus of my life.
