In the first sample for Isaiah chapter 45, the Lord makes a connection to the 45th book of the Bible with the question, “shall the clay say to him that formed it?”
ISAIAH 45:9 …Shall the clay say to him that fashioneth it, What makest thou?…
ROMANS 9:20 …Shall the thing formed say to him that formed it, Why hast thou made me thus?
21 Hath not the potter power over the clay…
The phrase “say to him” only appears TWO other times in the Bible (KJV) and both of them are in a command rather than a question.
In the second sample for Isaiah chapter 45, the Lord makes a connection to the 45th book of the Bible with every knee shall bow and every tongue confessing to God.
ISAIAH 45:22 …I am God…
23 I have sworn by myself, the word is gone out of my mouth in righteousness, and shall not return, That unto me every knee shall bow, every tongue shall swear.
ROMANS 14:11 For it is written, As I live saith the Lord, every knee shall bow to me, and every tongue shall confess to God.
The exact phrase “every knee shall bow” appears NO where else in the entire Bible (KJV).
The only other scripture that almost matches this phrase shows the deity of Christ.
That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father. (Philippines 2:10, 11)
In the third sample for Isaiah chapter 45, the Lord makes a connection by
offering salvation to ALL.
ISAIAH 45:22 Look unto me, and be ye saved, all the ends of the earth…
ROMANS 10:13 For whosoever shall call upon the name of the Lord shall be saved.
Isaiah chapter 45 has many other connections that deal with salvation, and Romans is the most used book in leading someone to salvation.
