God’s word says that we can know that we have eternal life!
These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life…1 John 5:13
God will not blot out any true believers name.
“He that overcometh… I will not blot out his name out of the book of life...” Revelation 3:5 / “Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?” 1 John 5:5
God’s power keeps us
Who are kept by the power of God through faith unto salvation ready to be revealed in the last time. 1 Peter 1:5/ My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand. John 10:29
We can’t break Gods seal
…in whom also after that ye believed, ye were sealed with that holy Spirit of promise…which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory. Eph 1:13-14
Can we take back what is no longer ours?
For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's. 1 Cor 6:20
Not every one that sayeth unto me, Lord, Lord shall enter…
… into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. Matthew 7:21
And then he will profess unto them, I never knew you: depart from me, ye that work iniquity. Matthew 7:23. This passage is not saying one can lose their salvation, but that God never new them to begin with. (See also Heb12:3-11)
We can’t buy our salvation (good works are the product not the means)
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. For we are his workmanship, created unto good works… Eph 2:8-10
Dose once saved always saved mean I can sin all I want? (no!)
What shall we say then? Shall we continue in sin that Grace may abound? God forbid. How shall we, that are dead to sin, live any longer therein?
This shows clearly that if you aren’t willing to live for God now how can you say that you were truly saved in the past?
God sent His son so that we could have Everlasting Life, the meaning of life everlasting is that it cannot and will not end. (see John 3:16)
