Spend it foolishly - Exodus 30-32

As Moses is getting instructions on what to build for a "tent of the meeting" and who will build it and how it will be built, the people are at the foot of the mountain preparing to disobey the very guidelines God is providing them to follow. The most obvious issue is that the only way they can build the items for the "tent of the meeting" is to collect all the gold and jewels they had and received from the Egyptians when they left that country. Yet, in Exodus 32 we read that the people gave Aaron some of the gold they had to make a molten image of a cow. Not only did they waste time worshiping a golden cow that couldn't even "moooo" they used valuable resources. These were resources God would want them to use to pour gold over the achaia wood they would make the ark, the poles and other consecrated items from. When we worship the wrong things we often spend valuable resources God has for us to spend on what He wants. We can waste those resources for our own pleasure or we can use them in a way that honors God. God can always provide more resources but what He does provide is for us to use to His glory, not our own fears and desires.
