Mark 2:5

When Jesus saw their ¹  faith, he said to the paralytic, “Son, your sins are forgiven.” ² 

Ge 22:12; Job 33:17-26; Ps 32:1-5; Ps 90:7-9; Ps 103:3; Isa 38:17; Isa 53:11; Mt 9:2; Mt 9:22; Mr 2:9,10; Mr 5:34; Lu 5:20; Lu 7:47-50; Lu 8:48; Joh 2:25; Joh 5:14; Ac 5:31; Ac 11:23; Ac 14:9; 1Co 11:30; 2Co 2:10; Eph 2:8; Col 3:13; 1Th 1:3,4; Jas 2:18-22; Jas 5:15

¹ sn The plural pronoun their makes it clear that Jesus was responding to the faith of the entire group, not just the paralyzed man.

² sn The passive voice here is a divine passive (ExSyn 437). It is clear that God does the forgiving.
