Love is the foundation of salvation by Grace
The love of God gives rise to His grace to save the entire willing world.
The love of God in us enables us to go Jesus for our salvation (John 5:38-42).
Jesus did come to save sinners (1 Timothy 1:15) but He did not come to save them without bothering with a bunch of rules or laws.
In Luke 5:32, Jesus says that He comes to bring sinners to repentance, that is, to stop behaving against Moses and the Prophets (Luke 6:29-31), to get baptized to become a brand-new holy (without sins).
As a foundation, Love saves good & bad men
All good and evil men were saved by grace before times eternal, that is, before men became either good or evil since men were not created yet.
Every person, who becomes good after our original death from acquiring knowledge of good and evil to die, was born evil because of the original sin, to learn how to do good and die doing good according to God in order to be saved.
Love does not excuse the human being who does not exercise the birthright to salvation by meeting the requirements of salvation to be eligible to claim it.
We must emulate the love of god to be saved
We need the love of God in us to be like God on earth to be saved.
Those who do not live according to Messianic (Christian) Judaism and do not believe that Jesus is YAHWEH do not have the love of God in them (John 8:24, 5:38-42).
(38) And ye have not his word abiding in you: for whom he sent, him ye believe not. (39)Ye search the scriptures, because ye think that in them ye have eternal life; and these are they which bear witness of me; (40) and ye will not come to me, that ye may have life. (41) I receive not glory from men. (42) But I know you, that ye have not the love of God in yourselves. John 5:38-42 ASV
Love is keeping 100% of the laws of Father God
There is no lawless salvation. For, loving God is doing all His holy, righteos, good laws.
(21) He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself unto him. (22) Judas (not Iscariot) saith unto him, Lord, what is come to pass that thou wilt manifest thyself unto us, and not unto the world?(23) Jesus answered and said unto him, If a man love me, he will keep my word: and my Father will love him, and we will come unto him, and make our abode with him. (24) He that loveth me not keepeth not my words: and the word which ye hear is not mine, but the Father’s who sent me. John 14:21-24 ASV
