Do you tremble or compalin after seeing God do some great thing? Exodus 13-16

Everyone has a different response to seeing a miracle of God.   We read that the nations who saw what God did to Pharaoh by drowning him and his army in the Red Sea "trembled" at what they saw (see 15:16).   However a few moments later, despite seeing the power of God, the nation of Israel "grumbled" because they had no water.  The grumbled because they had no food.  After seeing the power of God through the plagues on the Egyptians the unbelieving nations trembled.  But, the "believing" Israelites grumbled.   Not hard to see a lesson for us here.   How do we respond when we see the power of God demonstrated.   The disciples, after seeing Jesus feed 5,000 and 4,000 with a small resource meal and yet, baskets of left-overs, argued about what they would eat when alone with Jesus (see Mark 8).  The Galatians were soon to allow the false teachers to get them to return to "law keeping" instead of faith in Christ for their sanctification (see Galatians 3).   Our nature is to return to our flesh after we have experienced God's marvelous power in our lives.  In fact, it may be that after we have seen God's amazing power we are most vulnerable to flesh like issues; to complaining and sinning.   When faced with the emotion of sin in our face we need to take into a mental account of what God has done for us.  We need to make sure we don't succumb to the temptation of the flesh and give into grumpy behavior.   Let's have faith in God.  Even the wicked tremble when they see God do great things.  We ought to do more than complain for more.
