“Most assuredly, I say to you, he [or she] who BELIEVES in Me HAS everlasting life.” –JESUS, in John 6:47
“For GOD SO LOVED THE WORLD that He gave His only begotten Son, that WHOSOEVER BELIEVES in Him shall not perish, but have everlasting life.”
Moreover, brethren, I declare to you THE GOSPEL which I preached to you, which also you received and in which you stand, BY WHICH also YOU ARE SAVED, if you hold fast that word which I preached to you–unless you believed in vain. For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, and that He was buried, and that He rose again the third day according to the Scriptures,
1st Corinthians 15:1-4
In Him you also trusted, after you heard the word of truth, the gospel of your salvation; in whom also, HAVING BELIEVED, YOU WERE SEALED with the Holy Spirit of promise, who is the GUARANTEE of our inheritance until the redemption of the purchased possession, to the praise of His glory.
For by grace YOU HAVE BEEN SAVED THROUGH FAITH, and that not of yourselves; it is the gift of God, NOT OF WORKS, lest anyone should boast.
I marvel that you are turning away so soon from Him who called you in the grace of Christ, to A DIFFERENT GOSPEL, which is not another; but there are some who trouble you and want to pervert the gospel of Christ. But even if we, or an angel from heaven, preach ANY OTHER GOSPEL to you than what we have preached to you, let him be ACCURSED. As we have said before, so now I say again, if anyone preaches ANY OTHER GOSPEL to you than what you have received, let him be ACCURSED.
