Hebrews Series 3:1-6
John Owen gives an illustration of this problem from Israel collecting Manna. God sent Manna to Israel. They were to collect all that they needed and could use. If they collected but ended up not using the manna it turned putrid and filled with maggots. Likewise, God has given you manna from heaven (His Word). Whatever you collect must be used. Whatever you simply collect and don’t use will turn into putrid pride and filled with the maggots of self-righteous deception.
