1.Christ is knocking at my sad heart;Shall I let him in?Patiently pleading with my sad heart;O shall I let him in?Cold and proud is my heart with sin,Dark and cheerless is all within;Christ is bidding me turn unto him;O shall I let him in?2.Shall I send him the loving word?Shall I let him in?Meekly accepting my gracious Lord,O shall I let him in?He can infinite love impart,He can pardon this rebel heart;Shall I bid him forever depart,Or shall I let him in?3.Yes, I'll open this heart's proud decor,Yes, I'll let him in.Gladly I'll welcome him evermore;O, yes, I'll let him in.Blessed Saviour, abide with me,Cares and trials will lighter be;I am safe if I'm only with thee,O, blessed Lord, come in!
