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. (Matthew 24:14)
® the Gospel of God
For ye remember, brethren, our labour and travail: for labouring night and day, because we would not be chargeable unto any of you, we preached unto you the gospel of God. (I Thessalonians 2:9)
® the Gospel of Christ
And sent Timotheus, our brother, and minister of God, and our fellow labourer in the gospel of Christ, to establish you, and to comfort you concerning your faith: (I Thessalonians 3:2)
® Paul's Gospel
In the day when God shall judge the secrets of men by Jesus Christ according to my gospel.(Romans 2:16)
There is no contradiction here. God is the originator of the Gospel. Jesus fulfilled God's plan. Men like Apostle Paul are both recipients and messengers of the Gospel.
The Gospel is received by revelation from God. It is not a man-made doctrine:
But I certify you, brethren, that the Gospel which was preached of me is not after man. For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ. (Galatians 1:11-12)
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: And that he was seen of Cephas, then of the twelve: After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep. After that, he was seen of James; then of all the apostles. And last of all he was seen of me also, as of one born out of due time. 1 Corinthians 15:3-8
The Gospel is based on grace and faith.
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. John 3:16
Let not your heart be troubled: ye believe in God, believe also in me. John 14:1
Come unto me, all ye that labour and are heavy laden, and I will give you rest. Matthew 11:28
Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. Acts 2:38
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. Romans 10:9
In its widest meaning, it includes all Jesus taught about the Kingdom.
® The Gospel is the truth of God:
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. (Romans 1:16)
It is a fellowship of believers who have been born again and live in obedience to God. The word "Church" means "to call out from" or the "called out ones." The Church is composed of people called out from the Kingdom of Satan to the Kingdom of God. This includes people of every race, tribe, culture, and language who have accepted Jesus Christ as Savior.
Such words are sometimes used very broadly, but in their real definition include only those who have been born again through Jesus Christ and who are living in obedience to God.
The Bible uses several symbols which explain more of the nature, function, relationship, and position of the Church. In the following verses the Church is called:
The Temple Of God: Ephesians 2:21-22; I Corinthians 3:9,16; I Timothy 3:15; I Peter 2:5
A Royal Priesthood: I Peter 2:5,9; Revelation 1:6; 5:10
The Bride Of Christ: II Corinthians 11:2
The Household Of God: Ephesians 2:19
The Flock Of God: John 10:1-29; I Peter 5:3-4; Hebrews 13:20; Acts 20:28
The Church Of God: Acts 20:28; I Corinthians 1:2; 10:32; 11:22; 15:9; I Timothy 3:5; I Thessalonians 2:14
The Church Of The Living God: I Timothy 3:15
The Church Of Christ: Romans 16:16
The Church Of The Firstborn: Hebrews 12:23
The Church Of The Saints: I Corinthians 14:33
Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. John 14:6
