Trust in the LORD, and do good;
Dwell in the land, and feed on His faithfulness.
Delight yourself also in the LORD,
And He shall give you the desires of your heart.
Commit your way to the LORD,
Trust also in Him,
And He shall bring it to pass.
He shall bring forth your righteousness as the light,
And your justice as the noonday.
Rest in the LORD, and wait patiently for Him;
Do not fret because of him who prospers in his way,
Because of the man who brings wicked schemes to pass.
Cease from anger, and forsake wrath;
Do not fret—it only causes harm. (Psalm 37:3–8, NKJV)
Psalm 37 is another Psalm of David. We don’t know the particular circumstances around the writing of the Poison, but the theme of Psalm 37 is a comparison between the Righteous person, who trusts in the LORD, and the Wicked person, who despises God’s ways.
In verses 3–4, David explains that trusting in the LORD begins with delighting in Him. The idea here is for us to take great pleasure in the LORD. His value is beyond measure. So just as we might cherish a precious jewel, we cherish our fellowship with Him above all else. He is our source of joy and self-worth. He names us and calls us His own. So when David writes, “He shall give you the desires of your heart,” there’s two things going on. First, when we delight in the LORD, fellowship with the LORD is our greatest desire and as we draw near to Him, He draws near to us. Second, as we delight in Him and draw near to Him, His ways and His goals become our own. By humbling our hearts and entering His presence, we allow Him to fill us with joy, renew our hearts and minds making us more like Jesus, and guide our way according to His plans instead of our own.
In verses 5–6, David explains trusting the LORD in terms of a commitment to His ways. We know that the world systems are under the sway of the Enemy and all of creation is under the curse of sin. We also know, from the Word and from our own experience that in our hearts we want to live for Jesus, but these bodies of flesh carry our baggage of sin, always enticing us to turn against God’s ways. In our day-to-day lives, the only thing standing between a believer and sin is a commitment to the ways of the LORD. But we have to surrender to two truths. Trusting the LORD doesn’t start with commitment, it starts with delighting in Him, as David mentioned in verses 3–4. Second, commitment is an act of our will, but we are powerless to carry it out on our own strength. As David writes, “He shall bring forth our righteousness.” Indeed, the light in us is not our own, it is Jesus Christ, the light of all men, who covers us with His righteousness and who leads and strengthens us according to His ways.
In verses 7–8, David depicts our trusting in the LORD as resting in Him. Our English word “rest” has different meanings. David isn’t talking about taking a nap or taking a day off to watch Netflix. Now there’s nothing wrong with those things, per se. But the idea here isn’t physical rest, it’s spiritual. “Be still and know that I am God” says the LORD (Ps 46:10). And as David explains here, “Do not fret, … cease from anger, … forsake wrath.” It’s easy to look around us and see the hypocrisy of the world and the flaws in our brothers and sisters in Christ. But God doesn’t want you to change them. That’s His job and we partner with Him in that work primarily through prayer and gracious encouragement. No, God wants each of us to surrender our own hearts to Him so He can change each of us Himself. And He does this by filling us with His Holy Spirit who dwells within us and ministers to our hearts. When we’re sad, He’s with us, comforting us, if we’ll let Him. And when we’re angry, He’s with us, cooling our tempers and speaking His truth to us, if we’ll let Him.
In John 15, Jesus, at His last Passover meal with the Twelve, said, “I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without me, you can do nothing.” Jesus was talking in spiritual terms. In this world, without Christ, we can walk around and do this or that, helping people or taking advantage of them or whatever. But it all amounts to nothing apart from Christ. Eternity is real and the LORD wants us to enjoy it with Him. But at the same time, Hell is a very real place of torment created for Satan, the demons, and the fallen angels. If you don’t want to be with Jesus, He won’t make you be with Him. But the only other option is Hell. The beauty of the Cross is that enjoying Christ for Eternity is a gift that Jesus purchased for us and offers to us freely. Salvation cost Jesus an agonizing death by means of crucifixion. But salvation costs us nothing except to trust in Him. And that’s why we celebrate communion, to remember the price He paid at Calvary so that anyone and everyone who trusts in Him can enjoy His presence for Eternity.
