Test your ability to write the ten commandments down.  Can you? Remember that Jesus said in Matthew 19, "obey the commandments" and "If you want to be perfect, go, sell your possessions and give to the poor, and you will have treasure in heaven. Then come, follow me."

Well lets just start with the Commandments…  You cannot keep them if you do not know them.  Make sure that if asked, you have these memorized.

Exodus 20 (Amplified Bible)

 THEN GOD spoke all these words:

1. You shall have no other gods before or besides Me.
2. You shall not make yourself any graven image [to worship it] or any likeness of anything that is in the heavens above, or that is in the earth beneath, or that is in the water under the earth; You shall not bow down yourself 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 fourth generation of those who hate Me, But showing mercy and steadfast love to a thousand generations of those who love Me and keep My commandments.
3. You shall not use or repeat the name of the Lord your God in vain [that is, lightly or frivolously, in false affirmations or profanely]; for the Lord will not hold him guiltless who takes His name in vain.
4. [Earnestly] remember the Sabbath day, to keep it holy (withdrawn from common employment and dedicated to God).Six days you shall labor and do all your work,But the seventh day is a Sabbath to the Lord your God; in it you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, your daughter, your manservant, your maidservant, your domestic animals, or the sojourner within your gates.For in six days the Lord made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. That is why the Lord blessed the Sabbath day and hallowed it [set it apart for His purposes].
5. Regard (treat with honor, due obedience, and courtesy) your father and mother, that your days may be long in the land the Lord your God gives you.
6. You shall not commit murder.
7. You shall not commit adultery.
8. You shall not steal.
9. You shall not witness falsely against your neighbor.
10. You shall not covet your neighbor's house, your neighbor's wife, or his manservant, or his maidservant, or his ox, or his donkey, or anything that is your neighbor's.
