Justin, this is such a precious truth of the Word of God it is not surprising that it is attacked on many fronts. Perhaps those who oppose particular redemption do not fully understand that such an unbiblical belief is a direct assault on the very character of the Trinity and an attempt to “de-throne” Him from being totally soveriegn in all things concerning His creation. As with all things pretaining to Christ and His salvation this is something that must be revealed and made alive to the believer by the Holy Spirit.
Lord, glorify your Name and expose the evil.
