The Trinity doctrine is an illogical, non-Bible based teaching. Many are confused by this falsehood...and as a result do not feel close to God; or feel real love or real connection to/ for God because this erroneous teaching.John 7:29, is one of many verses in the Bible that disproves the Trinity doctrine.
You need to read holy Scripture carefully.
Prime factor of Holy Trinity. - One who calls everything into existence from nothing,The Supreme Majesty.
Yahweh
(One who calls everything into existence from nothing),God the father - is a spirit being,its beyond form and gender,not containable in heavens above heavens. John 4:24.
He is omnipotent,omniscient,timeless.We dwell in him.And by the term 'Him' it means supreme authority,not a man.
Second factor in Holy Trinity.(The Lord of Lords and King of Kings,don't assume its earthly kings,its about the leaders of heavenly and other spiritual host(armies and dominions) leaders.
Jesus Christ son of God(not physically begotten,but its a spiritual meaning) - Rev 1:5 KJV 1611.
He is the express image of God - Hebrews 1:3 KJV 1611.
By him(Amen,the Lord) God created everything. Revelation 3:14 KJV.
Don't think he is a creation.God created everything for Jesus.
In short,Jesus Christ is the wholeness of God in perfect form.
Our portal to reach God,with the help of divine channel called Holy spirit.
Third factor in Holy Trinity.- The Holy Spirit,Love of God given to us for our full spiritual growth to the image of Christ.
Holy Spirit is the caretaker given to us,after God made provision through crucifixion of Jesus and raising him up from death.
Its the same spirit of the Lord,mentioned in the Old Testament.The same spirit that was inside Samson,David,etc that lead them.In Grace Period that is now(ends with the Secret second coming of the Lord Jesus),Holy Spirit is at work. - Joel 2:28-32 KJV),John 16:7 KJV.
The beginning of the Mighty Pouring of Holy Spirit - Acts Chapter 2.Its called anointing of the Holy Spirit.Its with this supernatural strength the Early Apostles turned the world upside down.We don't much lean on God,so we doubt.
In short,the Trinity of God(Yahweh-God the Father,Jesus-God the son,Holy Spirit- God the spirit[the true good spirit] is like a family.A family is one but has different units.
Turn to God,Pray to Jesus.
God Bless.
