We are not under obligation to “explain” these truths [acts of God that make people emotionally uncomfortable]; we are only under obligation to state what God has revealed in His word, and to vindicate these statements as far as possible from misconception and objections.
In the nature of the case all that we can know concerning such profound truths is what the Spirit has seen fit to reveal concerning them, being confident that whatever God has revealed is undoubtedly true and is to be believed although we may not be able to sound its depths with the line of our reason.
In our ignorance of His inter-related purposes, we are not fitted to be His counselors. “Thy judgments are a great deep,” said the psalmist. As well might man attempt to swim the ocean as to fathom the judgments of God. Man knows far too little to justify him in attempting to explain the mysteries of God’s rule.
