Daniel Phillips: In case you’ve never read it, here is superb theologian/scholar Benjamin B. Warfield’s statement on how we find the doctrine of the Triune God in the New Testament:
We believe that Christ is coming again to judge the living and the dead. This promise is found throughout the inspired Scriptures. Till His return, believers are to live lives that bring glory to God through Jesus Christ. The Church is to be busy doing the work of evangelism and discipleship, proclaiming the pure, uncompromised Gospel of Christ by teaching the Word of God.
