Matthew 22:36-37
36 "Teacher, which is the great commandment in the Law?" 37 And He said to him, "'You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.' NAS
This is the foremost commandment given to mankind by God. All others are subordinate to this one. Jesus gave us a new commandment:
Matthew 22:38-39
38 "This is the great and foremost commandment. 39 "The second is like it, 'You shall love your neighbor as yourself.' NAS
However, Jesus also tells us that love when love of parents, siblings, etc. interferes with our love for Him we are not worthy of Him.
Matthew 10:34-39
34 "Do not think that I came to bring peace on the earth; I did not come to bring peace, but a sword. 35 "For I came to set a man against his father, and a daughter against her mother, and a daughter-in-law against her mother-in-law; 36 and a man's enemies will be the members of his household. 37 "He who loves father or mother more than Me is not worthy of Me; and he who loves son or daughter more than Me is not worthy of Me. 38 "And he who does not take his cross and follow after Me is not worthy of Me. 39 "He who has found his life shall lose it, and he who has lost his life for My sake shall find it.
NAS
How can we prove our love for Jesus?
John 3:36
36 "He who believes in the Son has eternal life; but he who does not obey the Son shall not see life, but the wrath of God abides on him." NAS
John 8:34-36
"Truly, truly, I say to you, everyone who commits sin is the slave of sin. 35 "And the slave does not remain in the house forever; the son does remain forever. 36 "If therefore the Son shall make you free, you shall be free indeed. NAS
John 8:50-52
50 "But I do not seek My glory; there is One who seeks and judges. 51 "Truly, truly, I say to you, if anyone keeps My word he shall never see death." NAS
John 14:21
21 "He who has My commandments and keeps them, he it is who loves Me; and he who loves Me shall be loved by My Father, and I will love him, and will disclose Myself to him." NAS
John 14:23-24
"If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him, and make Our abode with him. 24 "He who does not love Me does not keep My words; and the word which you hear is not Mine, but the Father's who sent Me.
NAS
You can attempt to lift “love your neighbor” above the greatest commandment and live in disobedience to Christ’s commandments (the Bible) but according to Jesus if you are disobedient you don’t love Him. This applies to men and women who live immoral lifestyles and moral men who judge those lost in sin, since only God has the authority to judge a man’s life.
We are told to correct those in the Body of Christ who live in unrepentant sin and if they refuse to confess their sin and turn from it, we are to exclude them from fellowship (1 Cor 5:9-13). Those outside the Body we are to love and preach (teach) the gospel.
Homosexuality is a sin according to God’s inerrant word. We can “love our neighbor” but love does not mean accepting the unacceptable.
