We have talked about how the name of God “Elohim” in Gen 1:1 allows for the New Testament revelation of the Trinity of the Godhead. Also, the use of the words “us” and “our” in verses like, “Let us make man in our image” agrees with this revelation. Even though the Old Testament and the New Testament are in agreement with this doctrine you will probably still run into opposition to this doctrine. Universalists, Jehovah’s Witnesses, and Mormons will strongly oppose this doctrine.
There is an easy to remember argument that you can make. Be confident in the truthfulness of the argument but also be aware that there are ready made answers using twisted interpretation. You don’t need to memorize the supporting verses, but reading over them to give you confidence of what the Bible says is helpful.
This argument says: When I read the Bible I see the Father, Son, and Holy Spirit involved in the Creation, the Baptism, the Resurrection, the Great Commission, in our Justification, in our Sanctification, and all of them live “in” us.
Event Father Son Holy Spirit
Creation Gen 1:2 Col 1:16 Gen 1:2
Baptism Luke 3:21 Luke 3:21 Luke 3:21
Resurrection Acts 3:26 John 2:19 Rom 8:11
Great Commisson Matt 28:19 Matt 28:19 Matt 28:19
Justified/Santified 1 Cor 6:11 1 Cor 6:11 1 Cor 6:11
Lives “in” us Eph 4:6 Col 1:27 Rom 8:11
I have never convinced anyone with this argument but at least I have an answer. Also interesting to note, people who don’t believe in the Trinity will agree with all the verses of the Father, but not the Son or Holy Spirit verses. So they have to twist at least 12 verses (there are many others) into meaning something other than what they plainly say. They have to work very hard to support what they want it to mean, while the doctrine of the Trinity is supported in the plain language.
Some other verses that support the Diety of Jesus are: John 5:19; 10:30-33; 17:5; 20:28; Romans 9:5; Phil 2:5-6; Titus 2:13 and 2 Peter 1:1.
