Change your life: Fill yourself with God’s Word.

We eat food a couple times a day and this gives our bodies the necessary fuel to function. You don’t eat food once a week or now and then. Our souls and inner life are fed by the truth of the Word. Don’t starve yourself and hinder your growth as a believer by snacking on the Word – feast on it, often.
 
“Meditate on these things; give yourself entirely to them, that your progress may be evident to all.”
1 Timothy 4:15 (NKJV) – emphasis mine
 
Meditating on God’s Word will bring fruitfulness to the degree that those around us will see the fruit. If we cannot see the blessings of God in our lives, then we have to ask ourselves if we’ve truly filled ourselves with God’s Word by meditating on it.
 
 “…but his delight is in the law of the Lord, and on his 

law he meditates day and night. He is like a tree planted by streams of water that yields its fruit in its season, and its leaf does not wither. In all that he does, he prospers.”
Psalm 1:2-3 (ESV) – emphasis mine
 
The fruit of meditating on God’s Word is that we are planted (established) “by streams of water” (we will never be thirsty or dry because God’s Word brings continual refreshing to our souls and life to our bodies). We will also experience the fruit of God’s Word (or seed) that we have planted in our hearts. Being full of the Word will cause us to prosper in all that we do (Deuteronomy 28:8).
 
Like physical exercise, meditation requires discipline to push through the natural resistance to it (largely due to our laziness and unfitness). When you start doing it, everything in and around you will try and distract you from following through – but the more you do it, the easier it gets.
