Sometimes we pray for a long time without seeing change. Consider the Israelites and have hope.
They cried for help. God heard, remembered his covenant and knew it was time to act. But first, He appeared to Moses and told him the rescue plan. When Moses went to Egypt, life got harder for the Israelites. Even Moses said, “You have done nothing to rescue them (Exodus 5:23)!” God sent ten plagues, one at a time. The Israelites journeyed to and then through the Red Sea. That was when they finally saw God’s answer to their prayers.*
*Read the whole story in Exodus 1 -15.
