You are adding to scripture.
Did you miss this:
John 15:10
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.
Romans 11
22Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you, provided that you continue in his kindness. Otherwise,
you also will be cut off.
2 Peter 2:20
If they have escaped the corruption of the world by knowing our Lord and Savior Jesus Christ and are again entangled in it and are overcome, they are worse off at the end than they were at the beginning.
Here are the sections from which you have chosen
single verses in three separate works:
1) “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."
I don't see how you miss the emphasis in this section on love! Just the first sentence is enough to explain the main subject. Jesus is telling his disciples that he and they are one, that he loves them, and considers them friends, not servants. The fact that you pull one single "if" sentence out of this shows your obvious bias against the message.
2) Here is the section from Paul's letter to the Romans containing your one verse...
"
I am talking to you Gentiles. Inasmuch as I am the apostle to the Gentiles, I take pride in my ministry in the hope that I may somehow arouse my own people to envy and save some of them. For if their rejection brought reconciliation to the world, what will their acceptance be but life from the dead? If the part of the dough offered as firstfruits is holy, then the whole batch is holy; if the root is holy, so are the branches.
If some of the branches have been broken off, and you, though a wild olive shoot, have been grafted in among the others and now share in the nourishing sap from the olive root,
do not consider yourself to be superior to those other branches. If you do, consider this: You do not support the root, but the root supports you. You will say then, “Branches were broken off so that I could be grafted in.” Granted. But they were broken off because of unbelief, and you stand by faith. Do not be arrogant, but tremble. For if God did not spare the natural branches, he will not spare you either.
Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you, provided that you continue in his kindness. Otherwise, you also will be cut off. And if they do not persist in unbelief, they will be grafted in, for God is able to graft them in again. After all, if you were cut out of an olive tree that is wild by nature, and contrary to nature were grafted into a cultivated olive tree, how much more readily will these, the natural branches, be grafted into their own olive tree!"
Clearly this section is telling the Gentiles that they should be grateful that they have been grafted into God's family, which stems from the root: Israel If they become ungrateful and arrogant about Israel, and live in unbelief as Israel did, they will be cut off. It is amazing that out of this poignant section about Israel being temporarily cut off from God you find a condemnation of all believers. That is really tragic!
3) The third section is taken from a discourse about
false prophets, and those who have followed them, not about true Christians.
"These people [false prophets] are springs without water and mists driven by a storm. Blackest darkness is reserved for them. For they mouth empty, boastful words and, by appealing to the lustful desires of the flesh, they entice people who are just escaping from those who live in error. They promise them freedom, while they themselves are slaves of depravity—for “people are slaves to whatever has mastered them". If they have escaped the corruption of the world by knowing our Lord and Savior Jesus and are again entangled in it and are overcome, they are worse off at the end than they were at the beginning. It would have been better for them not to have known the way of righteousness, than to have known it and then to turn their backs on the sacred command that was passed on to them. Of them the proverbs are true: “A dog returns to its vomit,” and, “A sow that is washed returns to her wallowing in the mud.”
It is amazing that you can apply these warnings to people who have abandoned Christ to all Christians.
Notice that Peter is talking about "them" not "us".
Be very cautious, my friend, about being self-righteous and threatening those who are perhaps weak in faith.
Build them up, don't threaten to tear them down.
It is obvious that you have taken single verses out of the context in which they were written, and with a pre-planned motive, warned the body of Christ about God's sternness toward them if they misbehave. Read Jesus' parable about the prodigal son if you want to understand God's forgiveness and love toward those who have
unintentionally made mistakes.
God is love!
