The Perfect Parent...what?

Where is the line between good parenting and bad parenting? I wish there was a line to draw, but I am beginning to realize that there is NO "perfect" parent out there who can parent perfectly. This is my current dilemma as I continue on my course of learning the how's, do's, and don't of raising children...but may I mind you, not just any children, but godly children.
I am in my 8th year of parenting and my 3rd year of raising godly children. With 5 years under my belt of the befores, I can definitely vouch that there is as big of a difference in the two parenting styles as night and day. As much as I try to be a "good" parent, sometimes I feel like I carry the title of a "bad" parent. Such a heavy burden.
"Am I a failure at this???"
"Should I give up on raising godly children and just go back to the befores?"
"Where is my help when I am all alone?"
"Where is the grace for my children's mistakes on their journey of growth?"
These are the questions that speed through my head amongst the jumbled clutter of a chaotic mind. The answer I get..."Be still and know...be still and know." Be still and know what? "That I am God." Now I am more than aggravated at the planet for my children's broken hearts and my over-bearing desire to give up along with my feelings of failure, but now I am aggravated at God for just telling me to sit down and shut-up like I am a little kid my self. Oh!!!!! Light bulb!!! I am a little kid! I am just a child to God and I am forever learning and being disciplined myself by THE perfect parent. And yes, I do need to sit down and shut-up. I need to leave my feelings of desolation and frustration out of the mix and leave it to God. I need to trust in HIM alone for my children. Seek HIM alone for the answers to my parenting questions and let HIM resolve any conflict that arises.
Tonight the kids and I studied Proverbs 10 and in just that one chapter, God spoke so many things; "the Lord does not let the righteous go hungry, " "hatred stirs up dissension, but love covers all wrongs," and "he who holds his tongue is wise." God is not going to let my prayers for my children be in vain, nor is he going to allow my efforts to raise godly children be in vain. Though other people may not grant grace to my children for their mistakes, they are only human facing their own trials in this same rotten world, but God gives them grace just as he gives me grace for not being a perfect parent. And if I hold my tongue not speaking in a manner that might be misconstrued, but be steadfast in prayer with patience and love, God's glory will be revealed.Thank you Lord that you are a God of patience, grace, and love. Help me Lord to see and love others the way you see and love them. Help me to parent my children according to your Word extending mercy and grace to them just as you have for me. Give me patience with each child and reveal to me which areas in each child's life that needs to be tended to at each particular moment that it is needed. Please fill myself and my children with your holy presence and may we be beacons for your kingdom.
