'Spiritual' in the Bible

And you will be hated by everyone because of [your association with] My name, but it is the one who has patiently persevered and endured to the end who will be saved.

For whoever has [spiritual wisdom because he is receptive to God’s word], to him more will be given, and he will be richly and abundantly supplied; but whoever does not have [spiritual wisdom because he has devalued God’s word], even what he has will be taken away from him.

Jesus answered him, “If you wish to be perfect [that is, have the spiritual maturity that accompanies godly character with no moral or ethical deficiencies], go and sell what you have and give [the money] to the poor, and you will have treasure in heaven; and come, follow Me [becoming My disciple, believing and trusting in Me and walking the same path of life that I walk].”
