2nd Corinthians 11:3-4, “But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ. For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.”
The Gospel is called “THE SIMPLICITY THAT IS IN CHRIST” (2nd Corinthians 4:4). We are saved by believing THE GOSPEL. Romans 1:16, “For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.” 1st Corinthians 15:1-4 defines “THE GOSPEL” as three things: Christ DIED on the cross for our sins, He was BURIED, and He RESURRECTED from the dead after three days. If you believe (trust) these truths, receiving Christ's sacrifice on the cross as payment for your sins, believing that He is risen, then you are SAVED my friend!!!
The Holy Bible tells what it means to “believe,” it means to “trust.” Ephesians 1:13, “In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise.” Isn't that so precious? The Bible makes everything so simple, if you just take it at face value, and don't let deeper-life theologians mess with your mind. Ephesians 1:13, “AFTER THAT YE HEARD THE WORD OF TRUTH, THE GOSPEL OF YOUR SALVATION: IN WHOM ALSO AFTER THAT YE BELIEVED, YE WERE SEALED WITH THE HOLY SPIRIT”!!! Folks, it's that simple to be born-again!!! The very moment that you place your trust in Jesus, in the Gospel, you are forever saved!!! You have eternal life!!!
Salvation is as simple as this: We are Hell-deserving sinners, and Jesus is the Savior. The big issue which needs to be dealt with in one's salvation is SIN. It is because of our own sins that we need salvation. Romans 6:23, “For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.” Many people trust upon some religious experience, or a prayer, or mass, or baptism, or church membership to save them. However, none of these things can take our sins away. Only through Christ, by the precious blood that He shed, can our sins be taken away.
