God does not save the unlucky person, even by His marvelous grace, who does not follow Him in obedience. You don’t just waltz in, say “Okay God. Looks good”, then walk out and do your own thing. The Godman Jesus said “Follow Me”. The concept of getting saved without then obeying and following Jesus is not in the Bible.
God is not reckless in any way
The God of the Bible is loving, and gives thought aforehand about all consequences of His actions. He knows what’s up before it happens, so nothing He does is “reckless”. God is not careless, hasty, impetuous, nor unwise. It’s not in His nature….” So why sing about a “reckless” God?
