The Trinity In The Bible
The New Testament does bring God (Father), the Son (Jesus Christ) and the Holy Spirit together in such a way as to strongly imply the Trinitarian nature of God. Three Scriptures are quoted below as a summary of the many other biblical passages that bring together the three Persons of the Godhead. One Scripture is from the Gospels, another is from the apostle Paul and a third is from the apostle Peter. The words in each passage referring to each of the three Persons are italicized to emphasize their Trinitarian implication:
All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit [Matthew 28:19].
May the grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with you all [2 Corinthians 13:14].
To God’s elect. . .who have been chosen according to the foreknowledge of God the Father, through the sanctifying work of the Spirit, for obedience to Jesus Christ and sprinkling by his blood [1 Peter 1:1-2].
Here are three passages in Scripture, one on the lips of Jesus, and the other two from leading apostles, each bringing together the three Persons of the Godhead in an unmistakable way.
But these are only a sampling of other similar passages. Among others are the following: Romans 14:17-18; 15:16;1 Corinthians 2:2-5; 6:11; 12:4-6; 2 Corinthians 1:21-22; Galatians 4:6; Ephesians 2:18-22; 3:14-19; Ephesians 4:4-6; Colossians 1:6-8; 1Thessalonians 1:3-5; 2 Thessalonians 2:13-14; Titus 3:4-6.
I encouraged you to read each of these passages and note how God (Father), Son (Jesus Christ) and the Holy Spirit are brought together as instruments of our salvation.
