and having been made perfect, he became the source of eternal salvation for all who obey him,
"Not everyone who says to me, "Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father in heaven.
Then the dragon was angry with the woman, and went off to make war on the rest of her children, those who keep the commandments of God and hold the testimony of Jesus.

…but anyone who loves God is known by him.
2 Thess 2:10
and with all wicked deception for those who are to perish, because they refused to love the truth and so be saved.
1 Cor 16:22
Let anyone be accursed who has no love for the Lord. Our Lord, come!
Blessed is anyone who endures temptation. Such a one has stood the test and will receive the crown of life that the Lord has promised to those who love him.
Has not God chosen the poor in the world to be rich in faith and to be heirs of the kingdom that he has promised to those who love him?
"Teacher," he said, “what must I do to inherit eternal life?” He said to him, “What is written in the law? What do you read there?” He answered, “You shall love the Lord your God with all all your heart, and with all your soul, and with all your strength, and with all your mind; and your neighbor as yourself.” And he said to him, “You have given the right answer; do this, and you will live.”
"If you love me, you will keep my commandments.
If you keep my commandments, you will abide in my love, just as I have kept my Father’s commandments and abide in his love.
But, as it is written, “What no eye has seen, nor ear heard, nor the human heart conceived, what God has prepared for those who love him”
If I speak in the tongues of mortals and of angels, but do not have love, I am a noisy gong or a clanging cymbal. And if I have prophetic powers, and understand all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but do not have love, I am nothing. If I give away all my possessions, and if I hand over my body so that I may boast, but do not have love, I gain nothing.
And now faith, hope, and love abide, these three; and the greatest of these is love.
LOVE IS OBEDIENCE
For the love of God is this, that we obey his commandments.
2 Jn 1:6
And this is love, that we walk according to his commandments; this is the commandment just as you have heard it from the beginning-you must walk in it.
By your endurance you will gain your souls.
For you need endurance, so that when you have done the will of God, you may receive what was promised.
Matt 24 :12-13
And because of the increase of lawlessness, the love of many will grow cold. But the one who endures to the end will be saved.
Therefore Jesus also suffered outside the city gate in order to sanctify the people by his own blood.
And now I commend you to God and to the message of his grace, a message that is able to build you up and to give you the inheritance among all who are sanctified.
To the church of God that is in Corinth, to those who are sanctified in Christ Jesus, called to be saints, together with all those who in every place call on the name of our Lord Jesus Christ, both their Lord and ours:
But now that you have been freed from sin and enslaved to God, the advantage you get is sanctification. The end is eternal life.
For the one who sanctifies and those who are sanctified all have one Father. For this reason Jesus is not ashamed to call them brothers and sisters,
And it is by God’s will that we have been sanctified through the offering of the body of Jesus Christ once for all.
who have been chosen and destined by God the Father and sanctified by the Spirit to be obedient to Jesus Christ and to be sprinkled with his blood:
2 Thess 2:13
But we must always give thanks to God for you, brothers and sisters beloved by the Lord, because God chose you as the first fruits for salvation through sanctification by the Spirit and through belief in the truth.
Clearly, your girl friends father does not believe that we are saved by “love alone”, “hope alone”, or “obedience alone.” Each of the above arguments shows that these kinds of things are necessary to salvation but none of them “alone” accounts for how we are saved. The argument for “faith alone” fails for the same reason that the arguments for “love alone” and all of the other arguments fail. These elements for salvation are not mutually exclusive and they all come from the same source. They are all by the grace of God, and all of the glory goes to God.
