You don't have to wait till you die to find out if you're saved! Once you've received Jesus Christ and you have Him in your heart, and you love Him and you know Him and you believe on Him as your Saviour, there are no if's, and's, or but's about it! You are a saved child of God! You have eternal life right NOW!--And you are the Lord's FOREVER! (Jn.1:12; 6:37; 10:38,39)
You already have Salvation! You don't need to worry about whether or not you are going to lose it, or how you are going to manage to STAY saved, because Eternal Salvation by Grace means ONCE saved, ALWAYS saved!--Besides, YOU can't keep yourself saved any more than you could save yourself in the first place! Only JESUS can do it! (Phi.1:6; 1Pet.1:5) So even though you're not perfect, and you're bound to make mistakes, God is going to save you anyway! Once you've received Jesus, you are completely purified and redeemed in the eyes of God by the sacrifice of CHRIST on Calvary!--That's the amazing Love of Jesus Christ and the Mercy of God! You're saved right now because God has promised it and God's Word is true!
Salvation is FOREVER! He's ALREADY given it to you and He's not going to take it back! It's YOURS! Praise the Lord!
