Read Psalm 37:16-20
When you look at the wicked and see their prosperity, don't fret or do anything foolish. The Lord is on your side, and "if God is for us, who can be against us?" (Rom. 8:31). In this passage God gives us all the assurance we need to have peace in our hearts. "A little that a righteous man has is better than the riches of many wicked" (v. 16). Here is your first assurance: God knows how much we need, and all of His wealth is available to us. What good is it to have a million-dollar house if it's not a home? What good is it to have a huge bank account if our values are not right? David is telling us that it's better to have a little and have God (because then we have everything) than to have much and not have God.
Our second assurance is that God knows how much we can take. "For the arms of the wicked shall be broken, but the Lord upholds the righteous" (v. 17). He knows how great a burden we can bear, how fierce a battle we can fight. When God puts us in the furnace, He always keeps His eye on the clock and His hand on the thermostat.
Third, God knows the days that we will live. "The Lord knows the days of the upright, and their inheritance shall be forever" (v. 18). He has a plan for your life. That sounds like a Christian cliche, but it's true. Whenever we've gone on trips, I am assured to know that the tour guide knows where he's going and what he's doing. I can just sit back and let him do the driving and the worrying. That's how God wants us to live. He wants us to leave everything with Him, because He knows how much we need, how much we can take and what will happen each day. Don't worry; live a day at a time. God's Word is clear, "As your days, so shall your strength be" (Deut. 33:25).
Take comfort in knowing that God is intimately aware of your needs. He knows what you need and what your limits are. Do you have pressing needs? Leave them with Him. Trust Him to provide them and resist the urge to look ahead and worry. Concentrate on what God is doing for you today.
