This message examines the brief period from Israel's triumph at the Red Sea until the nation's arrival at Mount Sinai. That period consisted of five "testing" episodes - episodes in which God tested His newly-redeemed "son" and Israel tested God. Together, these tests highlight a chosen nation perpetually marked by the failure of unbelief and rebellion. From the other side, they display a God of impeccable integrity who remains faithful to His covenant purpose and promises despite the incapacity, disobedience and unworthiness of the recipients of His covenant and its blessings. This historical interval between Egypt and Sinai provides a crucial context for the covenant at Sinai, establishing the reader's expectation of how both covenanting parties will perform under the covenant.
