The Risen Christ is Faith's Reality. And in 1 Corinthians 15:1-4 Paul lays out the reality of the Gospel in plain language, 

"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,"

The message of the cross is simple and pure and able to transform the ungodly into the righteousness of Christ unto salvation for all who believe.
