Why would God accept us as we are sinful and with our faults?
Why then do we go to confession before receiving the sacraments?

Because God possesses Holy Mercy, Mercy in its’ most complete and perfect form,

we need to go to confession because we need to be in a state of Gods Grace to receive the Sacraments, and to do this we need to be free of sin, esp. Mortal sin which destroys the life of Grace within us. I hope this is enough info for you!
