What Almighty God Can't Do
"And the angel [i.e. Gabriel] said to her, "Do not be afraid, Mary, for you have found favor with God. And behold, you will conceive in your womb and bear a son, and you shall call His name Jesus. He will be great, and will be called the Son of the Most High; and the Lord God will give to Him the throne of His father David, and He will reign over the house of Jacob for ever; and of His kingdom there will be no end." And Mary said to the angel, "How shall this be, since I have no husband?" And the angel said to her, "The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore the child to be born will be called holy, the Son of God. And behold, your kinswoman Elizabeth in her old age has also conceived a son [i.e. John The Baptist]; and this is the sixth month with her who was called barren. For with God nothing will be impossible." (Luke 1:30-37 RSV)
All Good Things Are Possible
Almighty God created the universe and all that is in it; there is nothing good that God cannot do. But God cannot lie, God cannot sin, God cannot violate His Own Laws. God is not a hypocrite.
"So when God desired to show more convincingly to the heirs of the promise the unchangeable character of His purpose, He interposed with an oath, so that through two unchangeable things, in which it is impossible that God should prove false, we who have fled for refuge might have strong encouragement to seize the hope set before us" (Hebrews 6:17-18 RSV)
"Let no one say when he is tempted, "I am tempted by God"; for God cannot be tempted with evil and He Himself tempts no one; but each person is tempted when he is lured and enticed by his own desire." (James 1:13-14 RSV)
Godly righteousness is summed up by The Ten Commandments. All other laws of morality (defined as "concern with the distinction between good and evil, or right and wrong; right or good conduct"), if they are truly moral laws, stem from the Ten Commandments - from the most literally obvious, such as prohibiting murder, to the everyday mundane, such as prohibiting the exceeding of the speed limit while driving, which if violated, is coveting and idolizing a destination (an actual place, or to just be "ahead") at the expense of the safety of everyone (i.e. disregarding love for one's fellow man), and can be murder (i.e. the unlawful destruction of life) when the inevitable mistake happens, by one driver or another, that cannot be safely overcome due to excessive speed (i.e. the reason for speed limits). A police officer with a radar gun is defending the principles of the Ten Commandments as much as he is enforcing municipal traffic laws.
Commandments One to Four:
How To Properly Worship The Only True God
"I am The Lord your God, Who brought you out of the land of Egypt, out of the house of bondage. You shall have no other gods before Me."
"You shall not make for yourself a graven image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth; you shall not bow down to them or serve them; for I The Lord your God am a jealous God, visiting the iniquity of the fathers upon the children to the third and the fourth generation of those who hate Me, but showing steadfast love to thousands of those who love Me and keep My Commandments."
"You shall not take The Name of The Lord your God in vain; for The Lord will not hold him guiltless who takes His Name in vain."
"Remember the Sabbath day, to keep it holy. Six days you shall labor, and do all your work; but the seventh day is a Sabbath to The Lord your God; in it you shall not do any work, you, or your son, or your daughter, your manservant, or your maidservant, or your cattle, or the sojourner who is within your gates; for in six days The Lord made heaven and earth, the sea, and all that is in them, and rested the seventh day; therefore The Lord blessed the Sabbath day and hallowed it."
Commandments Five to Ten:

(Exodus 20:2-17 RSV)
