I love this verse. It's one of my personal favorites. It shows how a Christian can live a "victorious life" DAILY!
A lot of references come to mind: Psalm 119:11; Psalm 1:2,3; Psalm 119:130; Hebrews 4:12. May I recommend you take time and look these up? What they show is that the "good treasure" of the "good man" in our Daily Verse is none other than the Word of God! When you "hide" God's Word in your heart, you are storing a "treasure" in your heart that truly takes control of your life.
Think of how "treasure" and wealth have affected people. Some rich people can never get a good night's sleep. They're constantly worried about their wealth! (Seems ironic, doesn't it. Most people would think a rich person has no worries. Don't you believe that!) Also, too many people who treasure the treasures of this world can never seem to be satisfied. A certain wealthy man was once asked, "Now that you have so much, what more do you want?" His reply was, "I want more!" Sad!!
But a Christian has greater treasure in the Word of God than any billionaire can possibly imagine, unless they are a believer! Psalm 119:72 says, "The law of Your mouth is better to me than thousands of coins of gold and silver." The wealth of the Word of God in your heart takes control of your life! A good treasure in your heart leads to a good walk with the Lord, and that can be daily, if you do what Psalm 1:2 says, "But he delights in the law of the Lord and in His law does he meditate day and night."
You want a victorious life? Spend time with the "...sharp two-edged sword..." of Hebrews 4:12. That will surely give you the victory as you face temptation and sin. God's Word in your heart will produce you godly character in your life!
