On the extent of who will be saved, the Bible makes two clear points: God desires that all sinners be saved (1 Timothy 2:4; 2 Peter 3:9; Ezekiel 18:23; Matthew 23:37).
First Timothy 2:4, 2 Peter 3:9, Ezekiel 18:23, and Matthew 23:37 are the texts most commonly cited to show that God's will is for all people to be saved and none to be lost.
According to Arminianism, God won't save all because to do so would require that he intrude upon and override the rebellious will of many unbelievers. God so values the purported dignity of libertarian freedom that he chooses only to save those who believe, although it would be possible to save those who don't as well.
Matthew 28:18-20
We must rejoice in the fact that we are saved. However, our salvation must not rest with us. We are to spread the good news about the salvation to others so that they shall also be saved.
You rescue the poor from those too strong for them, the poor and needy from those who rob them.” “Because the poor are plundered and the needy groan, I will now arise,” says the LORD. “I will protect them from those who malign them.”
“This is what the LORD says: 'Do what is just and right. Rescue from the hand of the oppressor the one who has been robbed. Do no wrong or violence to the foreigner, the fatherless or the widow, and do not shed innocent blood in this place.
Our recognition of God's sovereign initiative and rich mercy in saving undeserved sinners brings Him glory. Also, we should see that God desires His people to be workers of righteousness. Although we aren't saved by our works, we are saved in order that we will work for God. This is the point taught in Ephesians 2:10.
So, can God save non-Christians? Yes. This is one of several reasons that we are called to treat other faiths and people of other faiths with respect. But this doesn't lessen our call as Christians to share, with respect and love, that path that God has shown to us.
Jesus Christ is the one who saves because he saved us from the evil one (the devil). God is Almighty, and we should thank God every day for saving our lives. God is the only god that saves.
In desperation the jailer asked, “Sirs, what must I do to be saved?” Never missing an opportunity to share the good news, Paul and Silas said, “Believe in the Lord Jesus, and you will be saved—you and your household.” And that night, as Paul and Silas shared “the word of the Lord,” salvation came to that jailer's ...
While Jesus told Nicodemus, “Amen, Amen, I say to you, no one can enter the kingdom of God without being born of water and Spirit” (John 3:5), he did not set baptism as a hindrance to salvation but just the opposite. We so often judge things by human standards, but God is not restrained by our standards.
8 For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, 9 not a result of works, so that no one may boast. 10 For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.
As he wills that all Men should obey him, so he wills that they should all be saved; because there is an inseparable Connection between Obedience and Salvation, and the one implies the other. Thus we are told, Act. 17. 30.
Only they who have heard and believed the gospel of Christ. Just prior to the Lord ascending into heaven, He told His apostles, “Go ye into all the world, and preach the gospel to every creature. He that believeth and is baptized shall be saved; but he that believeth not shall be damned” (Mark 16:15-16).
Love for us kept Jesus on the cross. There very clearly is a universal love of God for all of mankind, both saved and unsaved. We are all made in His image, and He loves us because of that rather than our cherubic smiles and Father's Day gifts.
“They are not of the world, even as I am not of the world” said Jesus in John 17:16.
God Is No Longer Holding Men's Sins Against Them
Sin will kill you, but it's no longer an issue between God and man. Although unbelievers aren't saved, their sin is forgiven.
2 Corinthians 6:14-18 KJV
Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
Christians believe they need salvation from sin because sin stops people from having a proper relationship with God. All Christians believe that Jesus saved people from sin (atonement) by his death on the cross. Catholics and Orthodox Christians believe that Jesus brings salvation through the sacraments of the Church.
One must come to Him for salvation
And there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved." This is so because no one else in history has done for man in regards to salvation what Christ has done.
Ephesians 2:8-9 KJV
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: not of works, lest any man should boast. What Gift Has God Given You? Jesus, I Need You!
Proverbs 24:11–12 Calls Us to Spread the Gospel
And Proverbs 24 makes clear that God is calling people to rescue them, to pull them back from death, to take the gospel, the good news of His love to them.
“Carry each other's burdens, and in this way you will fulfill the law of Christ.” We were never meant to do life alone. We need the love and care of others, as much as we are needed by others in the same ways.
Proverbs 19:17
He who has pity on the poor lends to the LORD: When we give to the poor (expressing our love and pity towards them), we aren't wasting our money. It is like lending money to the LORD Himself.
