Impasto is Italian for paint that has been thickly applied onto a surface so as to stand out and the paint can easily be felt in high relief.
Spiritually: As God’s works of art, He loves to thickly apply His word and manners onto the surfaces of our hearts and minds so that we stand out visible for Him to enjoy and for anyone else on earth to enjoy. Sincere Christians are canvases on which God’s righteousness is thickly laid on, and anyone will know Who “painted” us…impasto.
