It’s the Holy Spirit that convinces you to be saved, not encouragement from preachers. It’s a work of God, not man.

(Hebrews 1:3) Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high;

(Matthew 24:14)(Matthew 28:19)
*Israel rejected the gospel of the kingdom and Christ.

What is the gospel?

The gospel by which you are saved: (1 Corinthians 15:1-4) 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:
*There is only one gospel.

Les Feldick, “That’s the gospel, that’s the gospel. When you believe that Jesus Christ, the Son of God, the Creator of everything, went to that Roman cross and suffered and bled and died and arose from the dead in power and glory and you believe that without anything else. Then I can make a flat statement, your glory bound, your glory bound, and nothing will ever take it away. But it has to be real, it has to be genuine, you have to mean business with God, and expect it’s going to change your life. It can’t just be walking the isle, get baptized, join the church, and then continue on as always. It has to be a changed life…, but how does it come? By believing in that death, burial, and resurrection, plus, how much? Nothing, plus nothing.”

(Isaiah 1:9)(Galatians 1:6-9)(Acts 15:1-5)(2 Corinthians 5:14-17)
