What/Who can separate us from God's love?

That's a no-brainer. It's not rocket science. Our situations and circumstances now or in the future can not separate us from God's love. Noone can separate us. He loves us regardless of our cares, burdens and yes, even our sins, failures and faithlessness.

"For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come, nor height nor depth, nor any other created thing, shall be able to separate us from the love of God which is in Christ Jesus our Lord." Romans 8:38-39 NKJV
