If you love it let it go

So i am starting to understand this "if you love something let it go" theory, however the "if it comes back it's yours" is a part i am not sure i agree with.
If GOD is to be loved with ALL my heart soul and mind, then there is not any room for anything that is NOT of Him. Therefore, when i love something, i must let it go if it is not God. This makes sure that HE is on the throne and nothing else. And when i give up everything else, i am at peace, my soul finds rest when i do not strive for something other than God!But every moment spend on this fallen planet i find something that i need to surrender back to God. I need to continually consecrate myself to God. Though i have been able to spot things in my life quicker than i had (and to actually give them up instead of choosing to keep something between me and God), i know this is still a process. So let's be patient with one another when we see flaws, faults, or failings. Let's restore gently (Galatians 6:1). By all means, yes, please do point it out if i do not see it, but do so gently. Everything in love. And i will do the same. Keep God on throne, and He does not share that. Let go of anything you desire outside of Him and you will see how He is more than enough!
