Exodus 2:24 And God heard their groaning, and God remembered his covenant with Abraham, with Isaac, and with Jacob.
God’s people are being severely mistreated by the Egyptians. They cry out to God. He hears them. Not only does He hear them but He remembers His promises to them and then acts on His promises.
You are never alone. He is a God that sees and knows where we are. He is at work in our lives.
It is not a waste of time to cry out to God. He does hear. He does remember. He will work in our lives. You have His Word, His promises.
That is one of the reasons that I really like to get into the Bible. I want to know what He has promised. I want to have an idea of what I can expect based on His Word.
Spent time with God. Spend time in His Word. Spend time in prayer. Watch God work in your life!
