Did Jesus know His purpose before He came to earth?

Jesus knew His purpose before He came into the world, based on the fact that salvation through Jesus was ordained before the foundation of the world (1 Peter 1:19-20; Revelation 13:8; 1 Corinthians 2:7) and He existed before the world began (John 17:24).

Philippians 2:6-8 shows how Jesus was equal with God the Father and yet became one of us, and Hebrews 10:5 says, "Therefore, when He came into the world, He said: Sacrifice and offering You did not desire, but a body You have prepared for me."

And in Mark 10:45, Jesus said about Himself, "For even the Son of Man did not come to be served, but to serve, and to give His life a ransom for many.”

Even though He knew He would be crucified, He went to the cross willingly (John 10:18; John 15:13; 1 Corinthians 11:24) because of His love for us.
