Matthew 28:19 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…
John 14:16-17 And I will ask the Father, and He will give you another counselor to be with you forever – the Spirit of Truth. The World cannot accept Him because it neither sees Him nor knows Him, but you know Him for He lives with you and will be in you.
1Cor 12:4-6 There are different kinds of gifts, but the same Spirit. There are different kinds of service, but the same Lord. There are different kinds of working, but the same God works all of them in all men. (For more about this read verses 7-11 also).
2Cor 13:14 May the grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with you all.
Ephesians 4:4-6 There is one body and one Spirit – just as you were called – one Lord, one faith, one baptism; one God and Father of all, who is over all and through all and in all.
1Peter 1:1-2 To God’s elect, strangers in the world, scattered throughout Pontus, Galatia, Cappadocia, Asia, Bithynia, 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.
We like to say that God is three “persons” in one, yet He is all one God. His goal for us as mankind is constantly the same, the Trinity as a whole is out to redeem mankind from sin. Each “person” in the trinity has a different task in our redemption, but all have the same goal, and the same character. Although the trinity idea is very confusing to us as humans, it is part of God’s revealing of himself to us, and it shows that He is incomprehensible to us in some ways. However, God’s character is that of truth, therefore he can only present himself to us as he truly is, even when it is confusing. One way to look at the trinity is that “God is above is, Jesus is with us, and the Holy Spirit is within us.” (note: this is from Unger’s Bible Dictionary)
Think about the trinity and draw a picture that represents the idea of the trinity to you. Just as water can be in the form of water, ice or steam and still be water. The Father, Son and the Holy Spirit are all still God, even though they are in different forms, and have some individual traits. In Christianity the trinity is sometimes represented with a picture of a clover leaf.
For myself, I find it to be an awesome thing that such an incomprehensible God is wonderfully revealing himself to me over the span of my life.
