"Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God; and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus." Philippians
BINGO. Not to belabor an obvious point, but as parents we therefore cannot only "fall back on" our faith when things are bad, only to shove God aside at our convenience, because that would limit the ability of us and our kids to see God's grace at work in our lives. Paraphrasing Isaiah, if we do not stand firm in our faith we will not stand at all. When we fall, we have to keep getting up.
