Submitting to God-given authority attracts God's blessings and protection for our life. The prime example of resisting God's authority in the Bible comes from Korah's rebellion in Numbers 16....
In this Palm Sunday sermon, we see from John 12 that future glory comes through present suffering. Even Jesus was troubled by the thought of suffering, but God gives strength to endure.
In Numbers 14, the Israelites were prevented from moving into God's best plan for their future because they believed their fears rather than trusting God. Our struggle is very similar today.
