Heb 12:2, Heb 4:14, Heb 10:23, Phil 3:10-14, Deut 8:3, Jn 6:32-35
We need to deeply understand the work of Christ that Jesus did. (Heb 3:1, Heb 12:2)
Heb 3:1 Wherefore, holy brethren, partakers of the heavenly calling, consider the Apostle and High Priest of our profession, Christ Jesus;
Heb 12:2 Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God.
We must also firmly believe that Jesus is the Christ. (Heb 4:14, Heb 10:23)
Heb 4:14 Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast our profession.
Heb 10:23 Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;)
Also, we must preach that Jesus is the Christ, even if we suffer for the sake of preaching the gospel. (Phil 3:10-14)
Phil 3:10 That I may know him, and the power of his resurrection, and the fellowship of his sufferings, being made conformable unto his death; 11 If by any means I might attain unto the resurrection of the dead. 12 Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also I am apprehended of Christ Jesus. 13 Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before, 14 I press toward the mark for the prize of the high calling of God in Christ Jesus.
In addition, we must deeply understand that Jesus is the Christ throughout the Bible. The entire Bible is the word of life that reveals that Jesus is the Christ. (Deut 8:3, Jn 6:32-35)
Deut 8:3 And he humbled thee, and suffered thee to hunger, and fed thee with manna, which thou knewest not, neither did thy fathers know; that he might make thee know that man doth not live by bread only, but by every word that proceedeth out of the mouth of the Lord doth man live.
Jn 6:32 Then Jesus said unto them, Verily, verily, I say unto you, Moses gave you not that bread from heaven; but my Father giveth you the true bread from heaven. 33 For the bread of God is he which cometh down from heaven, and giveth life unto the world. 34 Then said they unto him, Lord, evermore give us this bread. 35 And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.
