The nature of the Father, Son and Holy Spirit is another subject and a big one at that.... But who is Jesus is what we are talking about...
Jesus is God ( most agree with that) 100% fully divine. And 100% fully human, how this happened and how it was able to be, i can't explain.
It had to be that way or our salvation was not possible.
For humans to be reconnected to God the divine. we needed Jesus to reach across the gulf that sin has made and hold the Father with His divine connection and hold us with the human connection. We are restored through Jesus.
Rev 3:5 He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels.
Mat_26:42 He went away again the second time, and prayed, saying, O my Father, if this cup may not pass away from me, except I drink it, thy will be done.
Luk_22:42 Saying, Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done.
Joh_5:30 I can of mine own self do nothing: as I hear, I judge: and my judgment is just; because I seek not mine own will, but the will of the Father which hath sent me.
Jesus had His own will, but showed us that following the Fathers will is the perfect way, but He did have his own will.
Jesus can't be the Father in human form, because Jesus stands before the father in Heaven as high priest and Jesus had to choose between His Fathers will and His own will. 2 separate beings. They are one in Character and one in their purpose and love for the universe, they are both perfect and Jesus reflected that to us so that we can see the Father in the life of Jesus.
when the sins of mankind were placed on Jesus, was Jesus separated from the Father for a time? Was Jesus guilty for a time. When we sin we are separated from God and the result is death. How did Jesus die? because of sin, which means the Father and Jesus were separated for a time. Jesus didn't die from the physical suffering, He was surprisingly dead way before the other 2 that were crucified. Jesus died from the separation caused by sin. Sin Killed Him.
1Jn 2:1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
1Jn 2:2 And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.
