Once in Christ in Christ Forever [EPUB ebook] 

There are really only two beliefs in the world. There are those who believe they can save themselves and those who believe they need a Saviour. Only Christianity offers a Saviour. And only the Christian gospel guarantees every believer a place in the Father’s house. Because ‘salvation is of the Lord’ – plus nothing! In spite of this, many Christians are plagued with doubts on this very subject. When your certainty of eternal salvation goes, your joy also goes. When your joy goes, so does your spiritual strength, because ‘the joy of the Lord is your strength.’ The author takes us right to the problem and carefully shows us from God’s Word the antidote to spiritual uncertainty. Readable and right on target.
