The Gospel Message
"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" (Rom. 1:16).
"Moreover, brethren, I declare unto you the Gospel which I preached unto you, which also ye have received, and wherein ye stand; by which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how 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" (1 Cor. 15:1-4).
The Gospel Mission
"And this Gospel of the kingdom shall be preached in ALL the world for a witness unto ALL nations; and then shall the end come" (Mt. 24:14).
"And He said unto them, Go ye into ALL the world, and preach the Gospel to EVERY creature" (Mk. 16:15).
"For the hope which is laid up for you in heaven, whereof ye heard before in the Word of the truth of the Gospel; which is come unto you, as it is in ALL the world; and bringeth forth fruit, as it doth also in you, since the day ye heard of it, and knew the grace of God in truth" (Col. 1:5-6).
If we are to proclaim the Gospel to EVERYONE (Mt. 28:19-20; Mk. 16:15-16; Lk. 24:45-47; Jn. 1:11-13; Jn. 3:14-17; Acts 2:38; Rom. 10:9-11; 2 Pet. 3:9; 1 Jn. 2:2), and the Gospel states that Jesus died for ALL those who hear the Gospel (Isa. 53:6; Jn. 1:29; Jn. 12:32; Rom. 5:18; 1 Tim. 2:6; 1 Tim. 4:10; Heb. 2:9; 2 Pet. 2:1; 1 Jn. 2:2), then Jesus must have died for ALL of mankind.
This is what the Word says, and it also says, "Let God be true, but every man a liar!"
