The Wilderness of Our Own Sinful Hearts

[John] Newton observed that like Israel on the banks of the Red Sea, the immature Christian thinks that his troubles are now over.  The strong arm of God has parted the seas for him and led him to safety, and he presumes that it will always be so.  He thinks that there is nothing left now but to walk through life with the victorious hand of God on his side, and then to inter heaven for ever.  He doesn’t yet know that, like Israel, there is a huge desert to cross before entering the Promised Land.  The desert he has yet to see and grapple with properly is the wilderness of his own sinful heart.
