Two of my favorite verses out of all the Psalms are found in Psalm 34:10 and Psalm 37:25. They both speak of our need and God's supply.
Psalm 34:10 tells us, "The young lions do lack and suffer hunger; but they who seek the Lord shall not be in want of any good thing." Have you experienced this supply in your life, no matter what you were lacking - food, finances, favor?
Psalm 37:25 reads, "I have been young, and now I am old, yet I have never seen the righteous forsaken, or their descendants begging for bread." Again, these verses speak of our lack and the Lord's provision.
In the New Testament, in Philippians 4:19, Paul reminds us that "My God will supply all your needs according to His riches in glory in Christ Jesus."
What is it that you need? Do you believe what these verses promise? David and Paul did, because they knew their God - His character and His ways. It's important for us to make a declaration of our faith before the supply arrives. That’s what real faith is - confident expectation. Once our need is already met, there is no need for faith. That's called sight!
In what area of life do you have a need right now? Can you, or will you, believe God for the supply before you receive it from His hand? As the lyric to a Christian song reminds us - “...When you can't trace His hand, trust His heart.”
