What shall we say then?

‘What shall we say then? That the Gentiles, which followed not after righteousness, have attained to righteousness, even the righteousness that is of faith. But Israel, which followed after the law of righteousness, hath not attained to the law of righteousness. Wherefore? Because they sought it not by faith, but as it were by the works of the law. For they stumbled at that stumblingstone; As it is written. Behold, I lay in Sion a stumblingstone and rock of offense: and whoever believeth on him shall not be ashamed.' (Romans 9:30-33 KJV)

'But what sayeth it (the righteousness which is of faith)? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; 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. For with the heart man believeth unto righteousness; with the mouth confession is made unto salvation.' 

(Romans 10:8-10 KJV)

'Wherefore, holy brethren, partakers of the heavenly calling, consider the Apostle and High Priest of our profession, Christ Jesus; Who was faithful to him that appointed him, as also Moses was faithful in all his house.' (Hebrews 3:1,2 KJV)

Therefore begin, or continue, to confess with your mouth the Lord Jesus daily, even throughout the day. This confession: the Lord Jesus and his testimony is made unto salvation.
