That, according as it is written, He that glorieth, let him glory in the Lord. It was this power which indited the harsh words spoken against God in Isaiah 36 and God distinguishes this harsh disposition as unbelief. The heart of spiritual rebellion and a hatred for Jesus and His grace. The false church appeals to personality in defending its cause in making a place for the toleration of lies about Jesus. Harsh words against God expose the wickedness of unbelief by granting to itself a power and trust above the grace of God.
Spiritual rebellion is no small thing for what is at stake is the eternal destiny of souls.
Tolerating false confessions about Jesus grace in the gospel is what God calls blaspheme . But thanks be to God that He has spared His elect from the slavery of satan and his delusive lie out of Hell, the lie of Tolerant Calvinism, the false gospel which cannot save. God sets His people free in Christ and they enjoy for eternity the position of a remnant unto glory. And our God certainly saves His chosen, each and everyone one of them. But thou, Israel, art my servant, Jacob whom I have chosen, the seed of Abraham my friend.
