Satan and this world's system wants your children. 

Key Verses: 

Exodus 10:8-11.  8 So Moses and Aaron were brought back to Pharaoh. “All right,” he told them, “go and worship the Lord your God. But who exactly will be going with you?”  9 Moses replied, “We will all go—young and old, our sons and daughters, and our flocks and herds. We must all join together in celebrating a festival to the Lord.”  10 Pharaoh retorted, “The Lord will certainly need to be with you if I let you take your little ones! I can see through your evil plan. 11 Never! Only the men may go and worship the Lord, since that is what you requested.” And Pharaoh threw them out of the palace.  

1 John 4:4-6. 4 But you belong to God, my dear children. You have already won a victory over those people, because the Spirit who lives in you is greater than the spirit who lives in the world. 5 Those people belong to this world, so they speak from the world’s viewpoint, and the world listens to them. 6 But we belong to God, and those who know God listen to us. If they do not belong to God, they do not listen to us. That is how we know if someone has the Spirit of truth or the spirit of deception.
