God has chosen to save all who believe in Jesus Christ for eternal life (Rev. 22:17). Calvinism is a lie that offers no assurance of salvation. The Bible teaches you can KNOW you have eternal life through faith in Jesus Christ (1 John 5:13). If you trust in the Lord, He will bring the right person into your life (one who is a born again believer).
Because we have all sinned against a perfectly holy and righteous God, we all deserve eternal separation from God in hell (Rom. 6:23). However, God loves us so much that He sent His only Son Jesus to die on the cross as our Substitute so we don't have to go to hell. Christ died for our sins, was buried, and rose from the grave three days later (1 Cor. 15:3-4). He gives eternal life freely to anyone who simply believes in Him. No one can be saved by doing good works. Salvation is by grace alone through faith alone in Christ alone (Eph. 2:8-9).
"Verily, verily, I say unto you, He that believeth on me hath everlasting life" (John 6:47).
