Hebrews 13:5-6
Let your conversation be without covetousness; and be content with such things as ye have: for He hath said, I will never leave thee, nor forsake thee.
So that we may boldly say, The Lord is my helper, and I will not fear what man shall do unto me.
What has God said about you, He hath said.... So that we may boldly say...
If He has said you cannot be sick, then you can declare, "I live in health everyday." If He has said you cannot be poor, then you can say, "I am rich and prosperous"
