How can we be saved? What are we saved from? Is there a key to achieving that salvation? These are all coherent questions that people ask each day, and all those questions have answers, but the truth is that there is no personal key for us to be saved, there is no effective method to achieve salvation , the only thing that can make us saved and completely free is the finished work of Christ on the cross.
The apostle Paul told us about this:
8 But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach;
9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
