How do we know that Christ is the one thing needful?

Christ's assertion that 'one thing is needful' in Luke 10:42 illustrates that amidst our many distractions and burdens, knowing and worshiping Him is essential. This perspective directs our focus away from earthly concerns and to our relationship with Him, which is central to our faith. In Him, we find everything necessary for salvation and acceptance before God, as John 10:28 declares that His sheep have eternal life, emphasizing His role as our primary source of comfort and strength.
