Is anything too hard for the Lord?

A verse highlighted in green caught my eye as I read my Bible today. The verse is found in Genesis 18:14 " Is anything too hard for the Lord? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son."

Is anything too hard for the Lord? - He created the heavens and the earth (Gen 1:1), He parted the Red Sea (Exodus 14), He sweetened the Bitter Waters of Marah (Ex 15:23-27), He provided Israelites with mannah and quails from heaven (Ex.16), He caused the water to flow out of the rock (Ex 17), He caused the sun and moon to stand still for the Israelites which led to their victory (Josh 9), with God's leading, the walls of Jericho fell down (Josh 6), He healed Naaman leprosy (2 kings 5) - considered incurable in those days and purposely instructed Naaman to dip in the dirty waters of Jordan River to show his power.He forgave a sinner 7 times (Mary), He stilled a storm, made the lame walk, raised the dead. He died and rose again. Seriously, Is anything too hard for the Lord?
