'Spiritual' in the Bible

For out of His fullness [the superabundance of His grace and truth] we have all received grace upon grace [spiritual blessing upon spiritual blessing, favor upon favor, and gift heaped upon gift].

For the Law was given through Moses, but grace [the unearned, undeserved favor of God] and truth came through Jesus Christ.

God is spirit [the Source of life, yet invisible to mankind], and those who worship Him must worship in spirit and truth.”

So when they had finished breakfast, Jesus said to Simon Peter, “Simon, son of John, do you love Me more than these [others do—with total commitment and devotion]?” He said to Him, “Yes, Lord; You know that I love You [with a deep, personal affection, as for a close friend].” Jesus said to him, “Feed My lambs.”

Again He said to him a second time, “Simon, son of John, do you love Me [with total commitment and devotion]?” He said to Him, “Yes, Lord; You know that I love You [with a deep, personal affection, as for a close friend].” Jesus said to him, “Shepherd My sheep.”
