'Man' in the Bible

You know that He appeared [in visible form as a man] in order to take away sins; and in Him there is [absolutely] no sin [for He has neither the sin nature nor has He committed sin or acts worthy of blame].

By this you know and recognize the Spirit of God: every spirit that acknowledges and confesses [the fact] that Jesus Christ has [actually] come in the flesh [as a man] is from God [God is its source];

No one has seen God at any time. But if we love one another [with unselfish concern], God abides in us, and His love [the love that is His essence abides in us and] is completed and perfected in us.

And we [have seen and] know [by personal experience] that the Son of God has [actually] come [to this world], and has given us understanding and insight so that we may [progressively and personally] know Him who is true; and we are in Him who is true—in His Son Jesus Christ. This is the true God and eternal life.
