This book is a primer, in three parts, dealing with God's Unity, God's Trinity, and God's Decree. Deity and Decree intends to teach the longstanding doctrine of God taught in the Christian church throughout the centuries. Christians who confess the Westminster Confession of Faith and the Second London Baptist Confession of Faith (1689) will find it especially pertinent to explaining the language and teaching of chapters 2 and 3 of those confessions of faith.
