Genesis 15:13 NIV
[13] Then the Lord said to him, “Know for certain that for four hundred years your descendants will be strangers in a country not their own and that they will be enslaved and mistreated there.”
The LORD prophesied to Abraham the 400 years of slavery the people of Israel would endure. This wasn’t a decree, but a warning. God warned Abraham, and in doing so, warned his future descendants. The LORD didn’t tell this to Abraham in order that it might be so, but told it to him so that he and his descendants would know. These 400 years of slavery, God even used as a foreshadowing of the 400 years of silence before the coming of the Messiah.
After Malachi, God stopped speaking, until 400 years later when John the Baptist came proclaiming, “Repent for the Kingdom of God is at hand.” Now, think about this, these 400 years of slavery could have been ended much sooner, but the Hebrews tried to withstand the oppression on their own in their own strength. The Hebrew midwives, instead of following Pharaoh’s decree of killing the baby boys when they are born, let the baby boys live. God, in turn, blessed them and gave them families. So, we know God was watching over His people and was faithful to them, but I want you to notice that it only mentions them crying out to God for deliverance after Moses flees Egypt, when Pharaoh dies, and their slavery became too much for them to bear on their own.
[23] During that long period, the king of Egypt died. The Israelites groaned in their slavery and cried out, and their cry for help because of their slavery went up to God. [24] God heard their groaning and he remembered his covenant with Abraham, with Isaac and with Jacob. [25] So God looked on the Israelites and was concerned about them.
Exodus 2:23-25NIV
In other words, if they had cried out to God sooner, they would have been delivered sooner. This is the same with us today. We overstay our welcome in places, begin to open doors in our lives, and become slaves to something. We try to fight it in our own strengt,h but it’s not until we cry out to the LORD Himself that we are delivered.
I believe DreamWorks truly nailed painting this picture when they wrote the song Deliver Us in their movie The Price of Egypt:
Deliver us
Hear our prayer
Deliver us
From despair
These years of slavery grow too cruel to stand
The length of our slavery to sin is always determined by how long we refuse to cry out to the LORD and seek His face for help.
When the LORD hears our cries, He answers our prayers. He comes to our rescue. He is faithful. He is just. He is love.
Dear LORD, I’m sorry for every time I did not call on Your name for help, but instead, tried to overcome and deal with sin in my own strength. Please come to my rescue. Deliver me from my sins. Cleanse me from all unrighteousness. Hear my prayer, oh LORD, and answer my call. Come to my rescue and be my strength. In Jesus’ name, I pray, amen.
