When God decrees that I be permitted to do some sinful action, he does so without coerision and for his own glory and with an interest in my ultimate good.
When I voluntarily act out what is within my heart, in opposition to God’s glory and to my own harm, then what I do is sin.
God does not sin in his decree but I sin in my act.
