There are also Scriptures that clearly state that Christ gave Himself for His Church:

Acts 20:28 Pay careful attention to yourselves and to all the flock, in which the Holy Spirit has made you overseers, to care for the church of God, which he obtained with his own blood.

Eph. 5:25 Husbands, love your wives, as Christ loved the church and gave himself up for her,
26 that he might sanctify her, having cleansed her by the washing of water with the word,
27 so that he might present the church to himself in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish.
28 In the same way husbands should love their wives as their own bodies. He who loves his wife loves himself.
29 For no one ever hated his own flesh, but nourishes and cherishes it, just as Christ does the church…

Here’s a rather lengthy quote from Dr. John Piper, that’s well worth considering. In commentating on the above verses he said, “There is a precious and unfathomable covenant love between Christ and His Bride, that moved Him to die for her. The death of Jesus is for the bride of Christ in a different way than it is for those who perish. Here’s the problem with saying Christ died for all the same way he died for his bride. If Christ died for the sins of those who are finally lost, the same way he died for the sins of those who are finally saved, then what are the lost being punished for? Were their sins covered and canceled by the blood of Jesus or not? We Christians say, “Christ died for our sins” (1 Corinthians 15:3). And we mean that his death paid the debt those sins created. His death removed the wrath of God from me. His death lifted the curse of the law from me. His death purchased heaven for me. It really accomplished those things!”

“But what would it mean to say of an unbeliever in hell that Christ died for his sins? Would we mean that the debt for his sins was paid? If so, why is he paying again in hell? Would we mean that the wrath of God was removed? If so, why is the wrath of God being poured out on him in punishment for sins? Would we mean that the curse of the law was lifted? If so, why is he bearing his curse in the lake of fire?”

He continues, “One possible answer is this: one might say that the only reason people go to hell is because of the sin of rejecting Jesus, not because of all the other sins of their life. But that is not true. The Bible teaches that the wrath of God is coming on the world, not just because of its rejection of Jesus, but because of its many sins that are not forgiven. For example, in Colossians 3:5-6, Paul refers to “immorality, impurity, passion, evil desire, and greed,” and then says, “On account of these things the wrath of God will come.” So people who reject Jesus really will be punished for their specific sins, not just for rejecting Jesus.”

“So, we go back to the problem: in what sense did Christ taste death for their sins? If they are still guilty for their sins and still suffer punishment for their sins, what happened on the cross for their sins? Perhaps someone would use an analogy. You might say, Christ purchased their ticket to heaven, and offered it to them freely, but they refused to take it, and that is why they went to hell. And you would be partly right: Christ does offer his forgiveness freely to all, and any who receives it as the treasure it is will be saved by the death of Jesus. But the problem with the analogy is that the purchase of the ticket to heaven is, in reality, the canceling of sins. But what we have seen is that those who refuse the ticket are punished for their sins, not just for refusing the ticket. And so what meaning does it have to say that their sins were canceled? Their sins are going to bring them to destruction and keep them from heaven; so their sins were not really canceled in the cross, and therefore the ticket was not purchased.”

“The ticket for heaven which Jesus obtained for me by his blood is the wiping out of all my sins, covering them, bearing them in his own body, so that they can never bring me to ruin can never be brought up against me again – never! That’s what happened when he died for me. Hebrews 10:14 says, “By one offering He has perfected for all time those who are sanctified.” Perfected before God for all time, by the offering of his life! That’s what it means that he died for me. Hebrews 9:28 says, “Christ also, [was] offered once to bear the sins of many.” He bore my sins. He really bore them (See Isaiah 53:4-6). He really suffered for them. They cannot and they will not fall on my head in judgment.”

“If you say to me then, that at the cross Christ only accomplished for me what he accomplished for those who will suffer hell for their sins, then you strip the death of Jesus of its actual effective accomplishment on my behalf, and leave me with what? An atonement that has lost its precious assuring power that my sins were really covered and the curse was really lifted and the wrath of God was really removed. That’s a high price to pay in order to say that Christ tasted death for everyone in the same way.”

Hebrews 10:
10 And by that will we have been sanctified through the offering of the body of Jesus Christ once for all.
11 And every priest stands daily at his service, offering repeatedly the same sacrifices, which can never take away sins.
12 But when Christ had offered for all time a single sacrifice for sins, he sat down at the right hand of God,
13 waiting from that time until his enemies should be made a footstool for his feet.
14 For by a single offering he has perfected for all time those who are being sanctified.

Did Christ’s sacrifice perfect for all time everybody on the planet (past, present and future)? Surely not, unless we believe in universalism (that everyone will be saved).

In John 15, Jesus taught us that true love can be seen in laying a life down for friends:
13 Greater love has no one than this, that someone lays down his life for his friends.
14 You are my friends if you do what I command you.
15 No longer do I call you servants, for the servant does not know what his master is doing; but I have called you friends, for all that I have heard from my Father I have made known to you.
16 You did not choose me, but I chose you…

In Galatians 2:20, Paul wrote, “I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me.”

Can a non Christian affirm that like Paul, he was crucified with Christ? Surely not!

The consistent theme of Scripture is the triumph of Christ’s all conquering work of redemption. When we are given a glimpse into the heavenly anthems sung by the redeemed, we read, “And they sang a new song, saying, “Worthy are you to take the scroll and to open its seals, for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation, and you have made them a kingdom and priests to our God, and they shall reign on the earth.” (Revelation 5:9-10)

Notice again the consistency of thought here. It does not say He redeemed everyone in every tribe, tongue, people and nation. Jesus, by His blood, actually redeemed people out of every tribe, tongue, people and nation.

The number of the redeemed is vast. Revelation 7:9-10 declares, “After this I looked, and behold, a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb, clothed in white robes, with palm branches in their hands, and crying out with a loud voice, “Salvation belongs to our God who sits on the throne, and to the Lamb!”

Scripture is explicit then in saying that Jesus died for His people, His sheep, His friends, His Church, securing eternal life for them in doing so.
