a stain or reproach (Job 31:7; Pr 9:7). To blot out sin is to forgive it (Ps 51:1,9; Isa 44:22; Ac 3:19). Christ's blotting out the handwriting of ordinances was his fulfilling the law in our behalf (Col 2:14).
Therefore, you people [must] repent [i.e., change your hearts and lives] and turn [back] again [to God] so that your sins will be blotted out and so that you may enjoy times of [spiritual] refreshment from the presence of the Lord [i.e., through the indwelling of the Holy Spirit].
He canceled the document written in ordinances [Note: This obviously refers to the Mosaic law] that was against us and was opposed to us, and has taken it out of the way, nailing it to the cross.
