No one should think they require to prove their love for God to anyone. However if someone claims to love God but doesn’t love their neighbor they’re probably lying.
I do not see it as an "either/or". Apparently, neither did Jesus:
"Master, which [is] the great commandment in the law? Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second [is] like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets." - Matthew 22:36-40 KJV
Both are required, but there is no shortage of those who do one but not the other. Likewise, there are many that claim to do both, yet do neither.
But it is also not my position to judge. I require no "proof".
