Matthew 6 : 31 - 34

Be not solicitous therefore, saying, What shall we eat: or what shall we drink, or wherewith shall we be clothed? For after all these things do the heathens seek. For your Father knoweth that you have need of all these things. Seek ye therefore first the kingdom of God, and his justice, and all these things shall be added unto you. Be not therefore solicitous for tomorrow; for the morrow will be solicitous for itself. Sufficient for the day is the evil thereof.

Romans 12 : 1 - 3

I beseech you therefore, brethren, by the mercy of God, that you present your bodies a living sacrifice, holy, pleasing unto God, your reasonable service. And be not conformed to this world; but be reformed in the newness of your mind, that you may prove what is the good, and the acceptable, and the perfect will of God. For I say, by the grace that is given me, to all that are among you, not to be more wise than it behoveth to be wise, but to be wise unto sobriety, and according as God hath divided to every one the measure of faith.

Romans 6 : 14

For sin shall not have dominion over you; for you are not under the law, but under grace.
