Jesus said if our faith in God was the amount of a little seed we could move mountains. Mountains like the biggest struggles in our lives.

Matthew 17:

19 Then came the disciples to Jesus apart, and said, Why could not we cast him out?

20 And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.

21 Howbeit this kind goeth not out but by prayer and fasting.

God’s people were slaves in Egypt. In their oppression they were forced to build great cities for the Kings of Egypt. In anguish they cried out to God. And God acted.

Exodus 2:

23 Years passed, and the king of Egypt died. But the Israelites continued to groan under their burden of slavery. They cried out for help, and their cry rose up to God. 24 God heard their groaning, and he remembered his covenant promise to Abraham, Isaac, and Jacob. 25 He looked down on the people of Israel and knew it was time to act.
