Those scriptures were in the Old testament, referring to God. Now we see New Testament writers declaring Jesus to be God.
You can read below Old Testament passages and then their direct references to Jesus as being God... the same God of the Old Testament.
Bottom Line Jesus is God!
1Timothy 3:16 And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory.
And this same Jesus wants you to be saved- saved from your sins(missing the mark of God) and saved from eternal death and separation from Him.
For God so Loved the world that He gave His Only Begotten Son that whosoever believes in Him should not perish but have everlasting life. John 3:16
We are born in sin and shaped in iniquity. In this state the only thing that we can have is death for the wages of sin is death.
But listen, the gift of God is eternal life. And this is in His Son Jesus who was crucified (John 19) but rose again from the dead (Luke 24) and is alive forevermore (Revelation 1:18)!
1 John 2:22-25 Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son. 23Whosoever denieth the Son, the same hath not the Father: (but) he that acknowledgeth the Son hath the Father also. 24Let that therefore abide in you, which ye have heard from the beginning. If that which ye have heard from the beginning shall remain in you, ye also shall continue in the Son, and in the Father. 25..And this is the promise that he hath promised us, even eternal life.
The term born again means that you have escaped death and have taken hold of life in Christ. You literally pass from death to life because you are born of Him and His righteousness and all that He is can be yours.
It's a divine exchange. He died and your sins and the sins of the whole world were upon Him. You receive Him and you get His life and His righteousness. All that is required is for you to believe on Him and confess Him.
Romans 10:13 "Everyone who calls on the name of the Lord will be saved.”
"that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved." - Romans 10:9
So, would you do that?
We all are in need of this precious gift. And the Lord Jesus' death on the cross, and resurrection from the dead and His ascension has afforded us the opportunity to be reconciled to Almighty God whereas before our sins separated us from Him (Isaiah59:2).
Then confess Jesus as Lord of your life and believe in your heart that God raised Him from the dead and you will be saved! It's simple.
This is the beginning. He will do the work in you as you yield to Him in your life in studying the Word and doing as He leads you by His Spirit.
