How can a young man keep his way pure? By living according to your word. I seek you with all my heart, do not let me stray from your commands. I have hidden your word in my heart that I might not sin against you. (Psalm 119:9–11, NIV 1984).
My Musings – To live according to His word, one must be familiar with it. Familiar enough that it is hidden deep within their heart. The firmer it is implanted, the less likely it is to stray and sin against Him. It’s not just for the young, but hopefully the mature are already firmly planted.
My Advice – Seek Him with all your heart. Reserving a portion of your heart for other “things” will lead you astray, because you cannot serve two masters. All in or not at all.
