In Exodus 16, God provided a miracle every morning: Manna from heaven. But along with the miracle came specific instructions. God wasn't just testing their appetites; He was testing their hearts. When we look at their mistakes, we see a mirror of our own struggles with trust and greed.
1. The Stench of "Holding Back"
In Exodus 16:20, God gave a simple command: gather only what you need for today. But some people tried to hoard it. They wanted a backup plan just in case God didn’t show up tomorrow.
The result? The extra food bred maggots and began to stink.
Disobedience has a smell. When we try to keep what God has told us to release—whether it's a "hoarding" mentality or, as you mentioned, trying to keep back part of a tithe—it doesn't lead to more. Instead, it "rots" our spiritual life. It doesn't work for our betterment; it just introduces a "terrible smell" into our relationship with the Father.
2. The Trap of the "Seventh Day" Hustle
In Exodus 16:27, we see the second act of disobedience. God told the people to rest on the Sabbath and focus on Him. Yet, some still went out to gather.
They couldn't stop the "hustle." This angered the Lord because He knew—even if they didn't—that man was made for rest. When we refuse to rest, we are essentially saying, "God, I don't trust You to provide while I'm still."
3. Disobedience as a Worship-Killer
Both of these moments hindered their worship.
You can't worship with a heart full of greed (the maggots).
You can't worship with a heart that won't rest (the Sabbath-breakers).
God doesn't want an empty offering; He wants an obedient heart. True worship happens when we trust Him enough to follow His instructions, knowing that His boundaries are there for our protection and our peace.
Reflective Questions:
The Manna Test: Is there an area of your life where you are "hoarding" (fearfully holding onto something) instead of trusting God for daily provision?
The Sabbath Test: Are you finding it hard to "stop the gather" and truly rest in Him? How might your busyness be hindering your worship?
