This is one of my favorite passages of scripture. Without getting into the deep context of the situation of Jeremiah and Israel, I like the word of God here. God has a plan for His people. His plans include to prosper His people. His plan does not include harm. In fact, God's plan for His people will be a future with hope. If you are in a storm right now in your life this passage probably speaks to you deeply. God does have a plan for our lives. Open your hearts and minds to Him. He will guide you in His righteous paths. Go in peace and go with God.
