Proverbs 31:6

Give strong drink unto him that is ready to perish, and wine unto those that be of heavy hearts.

Those described as ready to perish are souls in danger of spiritual ruin who stand in need of salvation. Their danger is to awaken a burden for them in others, moving those others to hunger and thirst for righteousness on their behalf. They require earnest labor put forth for their salvation. That labor brings relief to suffering bodies and to sin-sick souls while teaching Bible truth, so that physical health and spiritual health are restored together.
