Sevenfold Gifts of the Holy Spirit
"The Spirit of the LORD will rest on him—the Spirit of wisdom and of under-standing, the Spirit of counsel and of might, the Spirit of the knowledge and fear of the LORD—and he will delight in the fear of the LORD." - Isaiah 11:2-3
Only one thing is important -- eternal salvation. Only one thing, therefore, is to be feared -- sin. Sin is the result of ignorance, weakness, and indifference The Holy Ghost is the Spirit of Light, of Strength, and of Love.
With His sevenfold gifts (piety, wisdom, understanding, counsel, might, knowledge and fear of the Lord) He enlightens the mind, strengthens the will, and inflames the heart with God's love.
To ensure our salvation we ought to invoke the Spirit daily, for "The Spirit helps our infirmity. We know not what we should pray for as we ought. But the Spirit Himself asks for us."
