When God tells us to love others as ourselves (Le 19:18), there’s an implicit command to love ourselves, to treat ourselves and each other with honor and respect as children of JEHOVAH; the command is empty otherwise.
Unless we love ourselves, how can we love others? And if we don’t love others, how can we love God? (1Jn 4:20)
This isn’t about putting ourselves first (2Ti 3:2); self-focus can be strangely twisted, fearing success, prosperity, blessing, and envying those who find it. It isn’t even about liking ourselves, or thinking we’re better than others; that’s pride.
At it’s root, love is benevolence: desiring the best, for ourselves and others (1Co 10:24), seeking the well-being of all, the harm of none. (Php 2:15) It’s rejoicing in another’s prosperity and grieving in their loss. (Ro 12:15) It’s being aware of others, of what they’re perceiving and valuing, ever seeking to help them become their very best selves. (Php 2:4)
Loving God is loving what He loves, hating what He hates. (Ps 97:10) If God so loves each one of us that He’ll become our sin and die in our place, placing infinite value on every single human soul, we certainly ought to seek each other’s welfare, including our own. (1Jn 4:11) Seeking God, cleaving to JEHOVAH with all our heart and encouraging others to do the same, is the beginning of love (2Jn 1:6); there is no welfare outside Him. (Re 22:15)
Growing in God is growing in benevolence (1Th 3:12), becoming more like Him. (Mt 5:44-45) When I find myself disinterested in the welfare of another, or neglecting my own, Father, remind me of Your heart; Your arms are always open, inviting us all to come, and always will be. (Re 22:17)
