You need to get your assurance from God. Someone once said if you can be talked into getting saved, you can get talked out of getting saved.
"Now faith is the assurance of things hoped for, the conviction of things not seen. "
Hebrews 11:1
You need to know you have heard from God, and that you have His Holy Spirit of promise......
"And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal, the promised Holy Spirit, who is a deposit guaranteeing our inheritance until the redemption of those who are God’s possession—to the praise of his glory. "
Ephesians 1:13-14
Jesus said "seek, and you will find" - and I think sometimes that means we need to keep seeking until we do find. God wants you to have a strong unshakable assurance; but not such a one that causes you to presume upon him either.
