Exodus 16:20 Notwithstanding they hearkened not unto Moses; but some of them left of it until the morning, and it bred worms, and stank: and Moses was wroth with them.
God gave them manna to eat. He gave them sufficient for the day. Those that gathered a little less had enough. Those that gathered more had enough. When they tried to save it for the next day it bred worms and stunk. God didn’t want them saving for the next day. God wanted them to only gather extra for His day when they would be too busy worshiping Him to be gathering.
The lesson, it seems, is focus on the day in front of you. Do not be worried about tomorrow. I will give you enough to eat tomorrow. So you will not have to save extra. You will not need to be worried about the next day.
Jesus told His disciples that there was enough evil for one day. They were not to worry about the next day. I think we get in trouble when we do not focus on the day that the Lord has given us. I must do today what I should do and not worry about tomorrow. If I will trust God with today then He will take care of tomorrow.
Let’s trust God. He has gotten us this far and He will take us on!
