Jesus’ Sacrifice set us apart (sanctified) us in Him (Hebrews 13:12; John 17:19).
Our sacrifice must set Jesus apart  in us (John 17:19; Romans 1:1). This fulfills the first commandment. You shall not have any other gods before me, says God (Exodus 20:3).

Jesus’ Sacrifice demanded His life for us (Hebrews 10:1-18).
Our sacrifice MUST demand our life for Him. We must present ourselves as a living sacrifice to Him (Romans 12:1-2).

Point(s) to ponder:
Is our sacrifice for Jesus, as His is for us?

John 17:15-19 (KJV)
15 I pray not that thou shouldest take them out of the world, but that thou shouldest keep them from the evil.
16 They are not of the world, even as I am not of the world.
17 Sanctify them through thy truth: thy word is truth.
18 As thou hast sent me into the world, even so have I also sent them into the world.
19 And for their sakes I sanctify myself, that they also might be sanctified through the truth.

Romans 12:1-2 (KJV)
1 I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service.
2 And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
