In this passage, God is speaking through Isaiah to His people. I really love this passage because even though it's before Jesus, it foreshadows Him. It also talks about God as a savior. He loves them so much that He wants them to thrive on earth. He wants good things for His children. He wants beauty for ashes and joy for our sadness. He is telling these people, specifically the poor and needy, that there is good news coming.
these promises are for you
The Lord wants to do all of these things for you, too. He wants to bind up your broken heart, to proclaim freedom from that one certain sin over you, to release those of you who feel like prisoners to sadness or anger. If you're morning, He wants to be your comfort. He wants to replace your morning with true joy that can only come from Him. All of these promises are things He desires to do for you.
some practical steps
How do we recieve these promises? There is power in the word of God. This being said, a good place to start would be to read these promises out loud, speaking them over yourself. These can feel strange at first, but it is such a powerful tool. We can also ask God to replace our thoughts with His thoughts. Spend some time with the Lord, ask Him to show you how to live in these promises.
My prayer for you is this: I pray the good news of Jesus becomes real everyday to you. I pray God replaces your broken heart with His heart. I pray He brings joy for your mourning and praise for your sadness.
Ask, He listens.
