Yes, I have been taught in Sunday school the attributes of God, but these arr thr things I know from His Word. God IS: He exists in 3 persons: Father, Son, Holy Spirit. All three are represented at creation, (Genesis 1, John 1, Collosians 1). The "trinity" which is not a word found in the Bible is yet seen throughout Old and New Testaments. They are one and there is no division or double-mindedness to God. He is one and unified in deed and intent: Deuteronomy 6:4, "Hear, Israel: YHWH is our God: YHWH is one:", and Matthew 28:19, "baptising them in the name of the Father and of the Son and of the Holy Spirit", James 2:19, "You believe that God is one, you do well. The demons also believe and shudder."
Omnipotence. All are justified in believing God to be all powerful. Firstly, no one can empirically prove where the energy that is the source of all things resides. No one can prove these things either pro or con to God's claims, so since all of the prophesies in the Bible come to pass we are also justified in believing God is not a liar and can believe Him: Isaiah 44:24, "I am Yahweh, who makes all things; who alone stretches out the heavens; who spreads out the earth by myself", Hebrews 11:3, "By faith, we understand that the universe has been framed by the word of God, so that what is seen has not been made out of things which are visible", Isaiah 45:5, "I am Yahweh, and there is none else. Besides me, there is no God".
Omniscience. This we also know by prophesy and declairing of knowledge to the ancients that which we still discover. Isaiah 40:13-14, "Who has directed the Spirit of Yahweh, or has taught him as his counselor?
14Who did he take counsel with, and who instructed him, and taught him in the path of justice, and taught him knowledge, and showed him the way of understanding?", and 46:10, "Remember the former things of old: for I am God, and there is none else; [I am] God, and there is none like me;
10declaring the end from the beginning, and from ancient times things that are not [yet] done; saying, My counsel shall stand, and I will do all my pleasure".
Omnipresence. Here are just a few verses. Proverbs 15:3, "The eyes of the LORD are in every place, Watching the evil and the good", Colossians 1:7, "He is before all things, and in Him all things hold together.", and Psalm 139:7-10, "Where can I go from Your Spirit? Or where can I flee from Your presence? If I ascend to heaven, You are there; If I make my bed in Sheol, behold, You are there. If I take the wings of the dawn, If I dwell in the remotest part of the sea,
Even there Your hand will lead me, And Your right hand will lay hold of me".
These are all verses anyone can find in a rudementary Google search. But these are attributes nonetheless, of which He has many. There is His Holiness, His Righteousness, His Perfection, Wisdom, Knowledge, Patience, Kindness, Love, and Mercy. Yes, those last two are indeed my favorites, as they have direct application to me, besides this one: God is a Person and Personal. And back to the Trinity we go: He IS Persons, and personal. God has a personality...Thee Personality. He is close and knowable, he put on flesh and blood and poured out His life for me, and you.
Jesus sat and ate with men. He held them and taught them. He said He knocks and whomever opens He will sup with. His Spirit is ever close, His kingdom within us. This is not a distant God. He is no far away force, but He is closer than a brother. He has a heart, emotions, and can be grieved. He is more than loving, but is THE definition of love itself. He is more than truthful, but the source of all truth. He is more than living, but is the source of all life, and this life He gives without merit in and through the Son.
The question may truly be not, "Is He infinate?", but "in how many ways?" He is the source of all that is good, and like the source of a great river we may not comprehend the depths of His plentitude, but may ever drink of His glory: the glory shown in the face of our Lord Jesus Christ, the fulness of the Godhead bodily. God bless you.
