No one has seen God at any time; the only begotten God who is in the bosom of the Father, He has explained Him.John 1:18(NASB)
In the beginning there was nothing but God - Father, Son, and Holy Spirit inhabiting eternity, in a tri-unity of love. They were united in a blessed trinity of endless communion and sweetest fellowship.
The only begotten and eternal Son of God, Who forever rests in the bosom of the Father, became Jesus of Nazareth, the perfect Man, God incarnate. He was born of a virgin, suffered under Pontius Pilate, was crucified, dead and buried. He rose again on the third day breaking the power of sin and death and bringing those who would trust in His sacrificial death into a knowledge of the Holy, for He Himself was God's full and final revelation of Himself to mankind.
No one has seen God at any time, except the one and only begotten Son of the Father - and that eternal third Person of the Trinity was the unique member of the Godhead Who was chosen in eternity past to come to earth as a human being, and in every way to live and move and have His being like as we are, yet without sin, so that He would become the unique and only sacrifice for sin.
The glory of God may be seen in nature and His wonderful works may be experienced in history, but the essence of God is invisible to man - and yet Jesus Christ is the image of the invisible God and the express image of His Person.
The LORD Jesus has unveiled God to man. We cannot KNOW God unless we KNOW the Son for "no-one has seen God at any time; the only begotten God Who is in the bosom of the Father, He has explained Him to us."
Heavenly Father, thank You for revealing Yourself to me through Your only begotten Son, my Saviour Jesus Christ. Open my eyes to see You more. Open my ears to hear Your voice. Open my heart to understand Your desire for my life, and may I live a life that is pleasing to You. In Jesus' name I pray, AMEN.
