You CAN'T always get what you want...

...but you can get what you need.
In reading Psalm 37 this weekend, this is what swept over me. We really have been taking this verse, and most of scripture for that matter, out of context. It came about in the first few verses:
"Trust in the LORD, and do good; dwell in the land and befriend faithfulness. Delight yourself in the LORD, and he will give you the desires of your heart. Commit your way to the LORD; trust in him, and he will act." (verses 3-5, ESV)
Too many people look at the Bible and look at verses like these like God's blank check. They look at verses such as this as well as Deuteronomy 8:18, which in the NASB reads "But you shall remember the LORD your God, for it is He who is giving you power to make wealth, that He may confirm His covenant which He swore to your fathers, as it is this day." The KJV says the "power to GET wealth." They misinterpret these so easily: God's gonna make me rich. God's gonna give me my heart's desire. Then they get disappointed when they don't get rich.
Deuteronomy 8:18 says God gives you the ability to do work and produce income for your family. God's not promising you a life of wealth with this verse, it says that through Him is the ability to do work to put food on your table. Through him, you earn a living, and produce wealth.
Back to Psalm 37: Trust in the Lord, be faithful to Him. Delight in Him, and He will give you your heart's desire. In other words, align yourself with His ways of thinking. Seek what God wants for you and through you. If you seek selfish desires, that is not what God wants, that is what you want. If you seek His kingdom and advancing it, His desires become your desires. He will then give you your heart's desire, because at that point your heart is right, and He will give you the means to make that desire become a reality (See Matthew 6).
As it says later on in Psalm 37: "I have been young and now I am old, Yet I have not seen the righteous forsaken Or his descendants begging bread. All day long he is gracious and lends, And his descendants are a blessing" (v. 25-26, NASB). If you are seeking what God wants, and looking to serve Him by being generous and helping others, He will satisfy you and will not leave you begging. And as I've mentioned recently, He doesn't operate on our timetable. It may seem lean, but He knows what you need, just when you need it. Trust Him, praise Him, and serve Him. You will be pleased with the results.
