All have sinned, and all have opportunity for salvation

As it is written: There is none righteous, no, not one; There is none who understands; there is none who seeks after God. They have all turned aside; They have together become unprofitable; There is none who does good, no, not one. Romans 3:10-12

Therefore, just as through one man sin entered the world, and death through sin, and thus death spread to all men, because all sinned. Romans 5:12

...whoever calls on the name of the Lord shall be saved. Romans 10:13

...must the Son of Man be lifted up, that whoever believes in Him should not perish but have eternal life. For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. For God did not send His Son into the world to condemn the world, but that the world through Him might be saved. John 3:15-17

For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast. Ephesians 2:8-9
