God’s plan has a purpose, and all of God’s plans are good. God spoke His creation into existence because He had a specific plan, for a specific reason.
When we delight ourselves in God, spend time with Him and know His ways, He will give us the desires of our heart. But, if God’s Word is in us, and the Holy Spirit is guiding us, our desires will become what He desires for us.
We all need God’s plan, because it communicates His vision for us. And, the good work that He begins in us, He promises to complete it. God’s thoughts for us are of peace, and not of evil, and to give us a future and a hope.
