If we'll let the truths of Scripture fill our minds, guard our emotions, and influence our conduct, God will richly reward us. I'm talking about spiritual blessings here (though He at times chooses to bless materially as well). By reading and meditating on His Word, you'll learn to understand His ways. This isn't something we can figure out on our own, because His ways are unlike ours—they are higher, bigger, and eternal.
Also, your relationship with the Lord will grow increasingly more intimate because He chooses to reveal Himself to those who seek Him and obey His instructions. When you see that God always keeps His promises, your confidence in His faithfulness will soar. No matter what the situation, you'll know you can trust Him. Then He'll transform your worries into joyful anticipation about what He's going to do next in your life. Even if hard times await, you'll be convinced that the Lord will work them out for good.
A life grounded in truth is powerful. Those who live by the Word develop spiritual discernment, which guides their choices and guards against deception. Because they demonstrate wisdom and godliness, the Lord enables them to impact others greatly. Since He knows they can be trusted, He also gives them greater responsibilities and opportunities for service in His kingdom.
With all this available to us, wouldn't it be wise to invest our time and energy in building the truth of God's Word into our lives? The other activities which clamor for our attention seem so important or pleasurable, but none of them can offer us the spiritual riches of a life grounded in truth.
