So does He say it's possible for you to love others with the same redemptive love by which He saved from hell? If yes, your blood can save others?
The Love He gives us is only redemptive because He is not bankrupt, in fact He is the very light of life itself. The Love that is shown by a person who is redeemed by His act of Love is not less simply because the act does not have redemptive power, and so He says to us:
“I am the vine; you are the branches. If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing. If you do not remain in me, you are like a branch that is thrown away and withers; such branches are picked up, thrown into the fire and burned. If you remain in me and my words remain in you, ask whatever you wish, and it will be done for you. This is to my Father’s glory, that you bear much fruit, showing yourselves to be my disciples.
“As the Father has loved me, so have I loved you. Now remain in my love. If you keep my commands, you will remain in my love, just as I have kept my Father’s commands and remain in his love. I have told you this so that my joy may be in you and that your joy may be complete. My command is this: Love each other as I have loved you. Greater love has no one than this: to lay down one’s life for one’s friends. You are my friends if you do what I command. I no longer call you servants, because a servant does not know his master’s business. Instead, I have called you friends, for everything that I learned from my Father I have made known to you. You did not choose me, but I chose you and appointed you so that you might go and bear fruit—fruit that will last—and so that whatever you ask in my name the Father will give you. This is my command: Love each other." John 15
Where does it say their deaths showed their perfect love, same as Christ who perfectly loved by His death which saves from hell?
They laid down their lives for the sake of passing on the gospel of salvation to many.
"Greater love has no one than this: to lay down one’s life for one’s friends." John 15
The Apostles even did this for their enemies.
"But I tell you, love your enemies and pray for those who persecute you, that you may be children of your Father in heaven.....Be perfect, therefore, as your heavenly Father is perfect." Matthew 5
Are they necessary rather than contingent beings without whose death, gospel can't have been communicated? Where does it say their deaths brought the gospel to us?
Are you not impressed with their sincerity? All that any of them needed to do to save their lives was to deny the gospel. But because they did not there is a strong apologetic for the truth of the faith that they proclaimed.
Romans 13:10:"therefore love is the fulfilling of the law". Do you say law doesn't say to do works of love?
Love fulfills the Law because the Law shows us a base line of the displeasure of YHWH, and Love lies well above that baseline. We work not to fulfill the Law but to Love our Father.
Aren't you trying to do works of love feeling obligated to please God?
Not at all. I agree with Paul who writes:
“I have the right to do anything,” you say—but not everything is beneficial. “I have the right to do anything”—but not everything is constructive. No one should seek their own good, but the good of others. 1 Corinthians 10
You, my brothers and sisters, were called to be free. But do not use your freedom to indulge the flesh; rather, serve one another humbly in love. For the entire law is fulfilled in keeping this one command: “Love your neighbor as yourself.” Galatians 5
If God doesn't justify you based on your works of love (Galatians 2:16), how can you please God by your works of love? What difference do you see between God justifying you & being pleased with you?
My children are my children irrespective of what they do, and I love them. If they do things that I don't like I am displeased and saddened, but I still Love them. But if they do things that please me, because they Love me I am ecstatic in my pleasure and my heart is filled with joy.
Are they obligated to act in any particular way? No. Because I value their freedom of action and thus know that the good that they do is an act of Love rather than one of fear and obligation.
Our Father in heaven created us in His image and, in His image, this is the way we are.
