Jesus' sacrifice involved more that just the physical suffering he endured. For a time he took all our sin and guilt and was separated from God as a result. That is why he cried out, "My God, my God, why have you forsaken me?" This might not seem like much to us because we are all guilty of sin and being separated from God is normal for us but Jesus was sinless and had always enjoyed perfect fellowship with the Father so this was completely new to him. Since we have never experienced sinlessness we can't fully comprehend what Jesus would have to suffer from having out sins placed on him.
His invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.
