The all-power of God as Creator is demonstrated in His creating out of nothing. The Hebrew word 'bara' translated "created" (Genesis 1:1 ) indicated the initiation of the object, not manipulating it after its original creation. The original creations of God include the
heavens and the earth and all things therein as first brought into being.
This awesome demonstration of God's omnipotence took place in the undated past. In the present, the universe which God created declares that mighty demonstration of God's all-power, all-wisdom, all-goodness, His all glory (Psalm 19 :1 ). This continuing
showing forth of His handiwork makes the Creator God visible to all who would see, only the wilfully blind and spiritually blind, the Satan blinded, cannot see (Acts 28:26-27; 2 Corinthians 4:4 ).
There are two reasons given why God delivered Israel in spite of their provocations and unbelief (Exodus 14:11-12 ). Having just been delivered out of Egypt, the reasons for their incredibly rebellious conduct were:
They witnessed the miraculous plagues God wrought against Egypt, but did not perceive or know the nature of God, nor did they comprehend His purposes. Do you also lack understanding of God's dealings with you, because you do not know Him or His intentions, and
the place He has for you in His eternal plan?
How quickly they forgot God's mercies. What is not understood by us will not be retained in our memory. Failure to get to know God's laws leads to questioning His promises and power, and rebellion against His Word easily follows.
Notice that "nevertheless He saved them" - and that for two reasons.
God is true to His name, so He in mercy served them and saved them (2 Timothy 2:13 ).
What a glorious exhibition of omnipotence it was!
By doing as He willed, and willing to do mighty deeds. God showed by His acts something of His might, giving a glimpse of His unlimited power so that it is seen that all things are possible to Him.
Other demonstrations of His all-power on behalf of Israel are enumerated in:
(Exodus 16:12; Psalm 78:24; Exodus 16:4; Exodus 17:6). By His miraculous power He screened them in the desert from the sun, lit up the dark night with His light, fed them by raining food on them, gave abundant water in a parched land, from an impossible place - no
good thing did He withhold in displaying His grace and power. With the psalmist let us confess the glorious omnipotence of our God:
