No one has seen our Heavenly Father except the One Who is from Him. Jesus is the exact representation of Him. Jesus only says what He hears our Father saying, and only does what He sees our Father doing. He expresses the very character of God.
“He is the radiance of the glory of God and the exact imprint of His nature, and He upholds the universe by the word of His power.” (Hebrews 1:3)
