• God evaluates the heart, not external appearance (1 Sam 16:7). • Samuel initially judged incorrectly—proving human discernment is limited. • A pure heart is devoted, undivided, and aligned with God’s mission. • David was chosen not for appearance but for a heart yielded to God. • God transforms sick, divided hearts into pure ones through grace (Jer 17:9). • The Spirit empowers those who belong fully to God. • Our greatest obstacle to purity is divided loyalty.
