28 Can only Jesus forgive sins

Acts vs Psalm

The New Testament Book of Acts tells us:
That Jesus alone forgives sin

Wait a minute!

The Old Testament Psalm 103 tells us:
That God can forgive sin already



In the New Testament, only Jesus forgives sin. For example, in a letter by the apostle Paul, Paul says:

Colossians 1:14 The blood of Jesus, his Son, purifies us from all sin.

And the New Testament Book of Acts also tells everybody: 

Acts 4:12 Salvation is found in no one else, for there is no other name under heaven given to men by which we must be saved.

But the Old Testament Yahweh already forgives sin 

Psalm 103:2 Praise the LORD [Yahweh], O my soul, and forget not all his benefits -- 3 who forgives all your sins and heals all your diseases. ... 7 He made known his ways to Moses, his deeds to the people of Israel. ... 11 For as high as the heavens are above the earth, so great is his love for those who fear him; 12 as far as the east is from the west, so far has he removed our transgressions from us. 

Recap: The New Testament teaches the doctrine that only Jesus forgives sins. But the Old Testament includes a guide to remove (forgive) sin. It was in place already centuries before Jesus. Thus Acts vs Psalm.
