The reason why Jesus never married is that it would have disqualified Him from saving us. Because He would have been in a blood covenant with someone of the seed of man-making of the same nature. Jesus was the only person that was ever born of the seed of the woman. If He had married it would have been in covenant with sin.

The fallen man was already joined with sin, and this would have joined Jesus to sin through the covenant of marriage.
The Bible declares in 1 Corinthians 6:16-17 “Or do you not know that he who is joined to a prostitute becomes one body with her? For, as it is written, “The two will become one flesh.” But he who is joined to the Lord becomes one spirit with him.”

How come then Jesus was not born a sinner like everyone else? The reason is that He was born of the Word. The prophetic word that was given to Mary produced the seed through The Holy Spirit. The woman does not give life to a child, she only gives the seed a body. The man’s sperm gives life to the child.
Jesus got a body from Mary but He got His life from the spoken word of God.
