Jesus Christ brought the new covenant to the world. It is a covenant of Salvation...think about it.
[13] Enter ye in at the narrow gate: for wide is the gate, and broad is the way that leadeth to destruction, and many there are who go in thereat. [14] How narrow is the gate, and strait is the way that leadeth to life: and few there are that find it! [15] Beware of false prophets, who come to you in the clothing of sheep, but inwardly they are ravening wolves. Matthew Chapter 7.
