"I am only a little child and do not know how to carry out my duties." - 1 Kings 3:7
"My grace is sufficient for you, for my power is made perfect in weakness." - 2 Cor 12:9
"The Lord will fulfil His purpose for me; your love, O Lord, endures for ever - do not abandon the works of your hands." - Psalm 138:8
I am glad that it is "the Lord" who fulfils His purpose.. and that the final responsibility isn't on us.
