"a brother or sister is naked and destitute of daily food, and one of you says to them, "Depart in peace, be warmed and filled," but you do not give them the things which are needed for the body, what does it profit"         (James 2:15-16 NKJV)

The Gospel

The Bible is the Book of all  books. You can prosper, you can be healed, you can have wisdom,  could strengthen  your position to God, The more you read the more you get closer to Him. It is the best physical possession that a man has ever had.  You can buy it from any Christian store and you can get it free from the internet, But I suggest you to buy one, if you do not have one yet. Bible has a healing power, whenever I feel pain on my chest I will just put the bible on top of my chest and  pray, every time there is a disturbances in mind, same thing, I will put the bible on top of my chest.  The Bible is inspired by God, it is the living word of God everything we need is there all you need is faith on Him.
A covenant is a principle of relationship with God on the earth, conditions established by God under which man is to live with Him.
The gospel is not a covenant, but the revelation of the salvation of God. It proclaims the great salvation of God. We enjoy indeed all the essential privileges of the new covenant, its foundation being laid on God's part in the blood of Christ, but we do so in spirit, not according to the letter. Hebrews 8  is the source to read on the above statement.
