The problem
Romans 3:10
“As it is written, there is none righteous, no, not one”.
Romans 3:23
“For all have sinned, and come short of the glory of God”.

The Consequences
Romans 5:12
Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all people, because all sinned.
Romans 6:23
For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.

The Solution
Romans 5:8
But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.
Romans 10:9-11
If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved. 10 For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved. 11 As Scripture says, “Anyone who believes in him will never be put to shame.”
Romans 10:13
“Everyone who calls on the name of the Lord will be saved.”

Assurance
Romans 8:1-2. There is now no condemnation for those who are in Christ Jesus…
Romans 8:38-39
I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.
