When the Israelites complained that they did not have food in the Wilderness of Sin, God told Moses, "I will rain down bread from heaven and they shall go out and gather certain quota each day." (Exodus 16:4)
The Israelites had been used to eating Egyptian bread and they probably expected that God would also feed them with it in the wilderness.
However, He did not.
He gave them A small round substance which was as fine as frost. (Exodus 16:14) It was also Like white coriander seed and it tasted like wafers made with honey. (Exodus 16:31)
Though the Israelites ate bread in Egypt, this small, white, round substance they were collecting from the ground did not resemble Egyptian bread otherwise they would not have asked each other "What is it?" (Exodus 16:15) and called it "What?" (Exodus 16:31)
One of the lessons we can learn from this incidence is that when God is moving you from one stage of your life to another He can do things differently to what you have been used to signify that you are in a new phase of your life.
So if you have been used to eating Egyptian bread and God starts feeding you miraculously with "What?" (Exodus 16:31) or something that you do not understand, recognize that you are in a new season of your life and start looking forward to where God is taking you to rather than looking backward to where you ate Egyptian bread.
Another lesson we can learn is that God can begin doing things differently in your present so that He can help you break old habits that keep you chained to your past and build better habits that propel you towards your destiny.
For instance if God moves you from a situation where you Sat beside pots of meat and ate bread till you were full (Exodus 16:3) to a situation where you are picking "What?" (Exodus 16:31) from the ground, He may be trying to strengthen your faith in Him and in His ability to provide for you.
A third lesson we can learn is that God could be trying to remove the taste of things you were used to from your life so that He can help you acquire new tastes that will help adapt to where He is taking you in your future.
For instance, He could have made the "What?!!" (Exodus 16:31) taste like wafers made with honey (Exodus 16:31) so that He could put the taste of the Promised Land He was taking them to in their mouths since He had promised them it would be flowing with milk and honey. (Exodus 3:17)
Receive it with gratitude and trust Him.
Trust that as you continue using it to fill your need, God will make you understand how it all fits in the great life He has planned for you because He promises you, I know the thoughts I think towards you, thoughts of peace and not evil, thoughts to give you the future you hope for. (Jeremiah 29:11)
