That person is like a tree planted by streams of water,
which yields its fruit in season
and whose leaf does not wither—
whatever they do prospers. Psalms 1:3
The fruits of reading and meditating on the Word of God are subtle and not always apparent. The imagery of being fed and watered is apt because natural growth is subtle as well. But years of food and nourishment pay off in hefty dividends.
Daily study and meditation is a choice and a habit. There are many things that would keep us from this habit, but ultimately we must choose to sit down and make it happen.
I will say that the rewards are greater when the opposition is fiercer. If the enemy is trying to prevent you from spending time in the Word of God, he knows how the Word can transform your life and thinking. If he knows that, we should realize it even more.
