Sometimes our sins over shadows and clouds our mind and force to believe God cannot forgive us.
In fact our sin still make us go deep into sin.
Jesus' arm is still stretched towards you
He said come let us reason together even if your sin as red as crimson it shall be cleanse off you...
If we confess our sin he is faithful and just to cleanse us and to wash from all iniquities..

Just take that arm of love.
Remember, he is not like our earthly parent once forgiven he has forgotten it...
