Jesus HIMSELF taught us to go to the Father for forgiveness.
Yes, He most certainly did, and He also told us in the verse just before the one you emphasized -- "...forgive us our sins..." -- to also ask Our Father to "Give us each day our daily bread", but He was NOT telling us to never go shopping for our food, or to never make use of grocers (or some other human beings) to get our daily bread (or to avoid human spiritual teachers for spiritual bread).
Do you just wait indefinitely for God to hand you your daily bread directly each day, or do you sometimes go out shopping for groceries through various other human beings?
Jesus said to them again, Peace be with you. As the Father has sent me, even so I send you. And when he had said this, he breathed on them, and said to them, Receive the Holy Spirit. If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained.
Not if someone promises it to me as a gift, delivered daily.
1 John 1:9 If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
Ephesians 2:4-10 4 But God, being rich in mercy, because of the great love with which he loved us, 5 even when we were dead in our trespasses, made us alive together with Christby grace you have been saved 6 and raised us up with him and seated us with him in the heavenly places in Christ Jesus, 7 so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus.
8 For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, 9 not a result of works, so that no one may boast. 10 For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.
