Salvation is a gift from God!
For by Grace you are saved, through Faith, and this not of yourselves; it is the gift of God; not of works, that not any one should boast, for we are his workmanship created in Christ Jesus unto good works, which God prepared beforehand, that we should walk in them!
Ephesians 2:8-10​
God saves whomever He wills!
For he said to Moses: I will have Mercy on whomever I will have Mercy and I will pity whomever I will pity. So then, it is not of the one willing, nor of the one running, but of the one showing Mercy, of God!  
Romans 9:15+16
He whom God calls follows God!
(notice I didn't say; whomever​ God calls, or all who God calls, but him or her whom God personally, individually calls, because the scriptures says; many are called, but few are chosen.
Whoever is one of his sheep will; 1. hear the call 2. follow 3. God through Jesus Christ will give them eternal life, AMAZING GRACE!
             Jesus said;
​My sheep hear my voice and I know them and they follow me. And I give eternal life to them and they shall not perish to the age, never! And not anyone shall pluck them out of my hand.       John 10:27+28​
God's Grace is sufficient!
No matter how big or small a sinner you might be, God's Grace is sufficient for you and me, for Christ Jesus came into the world to save sinners, of which I'm a chief. Where sin abounded, God's Grace all the more abounded!
That as sin ruled in death, so also GRACE might rule through righteousness to eternal life, through Jesus Christ our Lord!
                                                                                            ​Romans 5:21​
Why Salvation is possible for us
But God shows his love for us in that while we were still sinners,
Christ died for us.​                       Romans 5:8
For I delivered to you as of first importance what I also received;​ that 
Christ Jesus died for our sins ​in accordance with the scriptures.                                                             1 Corinthians 15:3
      Why I need Salvation!
The wages of sin is death and I am a sinner,                    Romans 6:23
The soul that sins, shall die​                                               Ezekiel 18:20
If you break one commandment, you are guilty of breaking them all​.
                                                                                          James 2:10​
I'm guilty; for all have sinned and fall short of the glory of God​
                                                                                          Romans 3:23​
Of myself, I'm addicted to sin, a habitual sinner, a slave to sin and sinning worse and worse....​                                               Romans 6:20
I was dead in my sins, dead to God...                               Ephesians 2:1​
By nature I'm a child of wrath...​                                         Ephesians 2:3
Just like Adam, God said; don't do this...I did this...​          Romans 5:12
There is Salvation in one only!
Thereis Salvation in no one else, for there is no other name under heaven given among men by which we must be saved!       Acts 4:12
