'Reckless' in the Bible

For the Lord humbled Judah because of Ahaz king of Israel, for Ahaz had allowed unrestrained and undisciplined behavior in Judah and had been very unfaithful to the Lord.

Or [you have the untamed and reckless nature of] a wild donkey accustomed to the wilderness,That sniffs the wind in her passion [for the scent of a mate].In her mating season who can restrain her?No males seeking her need to weary themselves;In her month they will find her [looking for them].

For if you forgive others their trespasses [their reckless and willful sins], your heavenly Father will also forgive you.

But if you do not forgive others [nurturing your hurt and anger with the result that it interferes with your relationship with God], then your Father will not forgive your trespasses.

A few days later, the younger son gathered together everything [that he had] and traveled to a distant country, and there he wasted his fortune in reckless and immoral living.

And they, [the ungodly in their spiritual apathy], having become callous and unfeeling, have given themselves over [as prey] to unbridled sensuality, eagerly craving the practice of every kind of impurity [that their desires may demand].
