The Person of God
The study of God has been the ambition of philosophers, etc., for millenniums. Some sit and meditate and try to think into the realm of the eternal Being. The only true knowledge about God can be gained from the Bible.
John 1:18 "No one has seen God at any time. The only begotten Son, who is in the bosom of the Father, He has declared Him."
1 John 4:12 "No one has seen God at any time. If we love one another, God abides in us, and His love has been perfected in us."
Exodus 33:20 (God speaking to Moses) "But He said, 'You cannot see My face; for no man shall see Me, and live.'”
Exodus 33:23 "Then I will take away My hand, and you shall see My back; but My face shall not be seen."
Moses talked to God and saw a part of Him but did not see the Lord's face. Jesus who is God's Son came from heaven to reveal the Father God to us. Jesus speaking to Philip in John 14:7-11 says that Jesus is the revelation of God. Pagan wisdom says "Man, know thyself", but Jesus says, "Man, learn of the Father".
John 17:3 tells us that to know God and Christ His Son is to have eternal life, "And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent.". John 17:3 tells us that to know God and Christ His Son is to have eternal life.
