for, "Everyone who calls on the name of the Lord will be saved." Romans 10:13
Shall be saved - This is the uniform promise; see Acts 2:21; Acts 22:16, ""Arise, and be baptized, and wash away thy sins, calling on the name of the Lord." This is proper and indispensable because, (1) We have sinned against God, and it is right that we should confess it. (2) because he only can pardon us, and it is fit, that if we obtain pardon, we should ask it of God. (3) to call upon him is to acknowledge him as our Sovereign, our Father, and our Friend; and it is right that we render him our homage. Barnes' Notes on the Bible
If you call on God Almighty (e.g Adonai, Yahweh & Allah), then you are saved. In Islam, Prophet Muhammad pbuh will intercede for us on the Day of Resurrection. God will hear his prayers and will answer him "O Muhammad! Raise your head and speak, for you will be listened to; and ask, for you will be granted (your request); and intercede, for your intercession will be accepted."
Underscoring a major factor that can bring you God’s lasting approval, Joel stated: “Everyone who calls on the name of Jehovah will get away safe.” (Joel 2:32) Two apostles, Peter and Paul, quoted this vital requirement. (Acts 2:21; Romans 10:13) Paul added another facet to that exhortation when he asked: “How will they call on him in whom they have not put faith?” (Romans 10:14) As for you, surely you want to call on the name of Jehovah and exercise faith in him now and forever! Calling on Jehovah’s name involves more than just knowing and using God’s personal name. (Isaiah 1:15) The context of Joel 2:32 stresses true repentance and trust in Jehovah’s forgiveness. (Joel 2:12, 13) Calling on God’s name implies truly coming to know him, trust him, obey him, and put him first in our life. Yes, serving Jehovah becomes our top priority. That, in turn, greatly contributes to a satisfying and lasting life, which is a blessing from God.—Matthew 6:33.
