But what does it say? “THE WORD IS NEAR YOU, in your mouth and in your heart”—that is, the word of faith which we are preaching, that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you shall be saved; for with the heart man believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation. For the Scripture says, “WHOEVER BELIEVES IN HIM WILL NOT BE DISAPPOINTED.” For there is no distinction between Jew and Greek; for the same Lord is Lord of all, abounding in riches for all who call upon Him; for “WHOEVER WILL CALL UPON THE NAME OF THE LORD WILL BE SAVED.”
And being found in appearance as a man, He humbled Himself by becoming obedient to the point of death, even death on a cross. Therefore also God highly exalted Him, and bestowed on Him the name which is above every name, that at the name of Jesus EVERY KNEE SHOULD BOW, of those who are in heaven, and on earth, and under the earth, and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father. So then, my beloved, just as you have always obeyed, not as in my presence only, but now much more in my absence, work out your salvation with fear and trembling; for it is God who is at work in you, both to will and to work for His good pleasure.
Jesus said to her, “I am the resurrection and the life; he who believes in Me shall live even if he dies, and everyone who lives and believes in Me shall never die. Do you believe this?” She said to Him, “Yes, Lord; I have believed that You are the Christ, the Son of God, even He who comes into the world.”
[And Philip said, “If you believe with all your heart, you may.” And he answered and said, “I believe that Jesus Christ is the Son of God.”]
2 Chronicles 7:14
and My people who are called by My name humble themselves and pray, and seek My face and turn from their wicked ways, then I will hear from heaven, will forgive their sin, and will heal their land.
“But the things which God announced beforehand by the mouth of all the prophets, that His Christ should suffer, He has thus fulfilled. Repent therefore and return, that your sins may be wiped away, in order that times of refreshing may come from the presence of the Lord; and that He may send Jesus, the Christ appointed for you, whom heaven must receive until the period of restoration of all things about which God spoke by the mouth of His holy prophets from ancient time.”
1 John 1:7-9
but if we walk in the light as He Himself is in the light, we have fellowship with one another, and the blood of Jesus His Son cleanses us from all sin. If we say that we have no sin, we are deceiving ourselves, and the truth is not in us. If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness.
