How to Know When Someones Saved? When the spirit bears witness. A testimony is great but it doesn’t mean much because anyone can have one.
 
Hebrews 3:6, 14
 
Once you’ve been saved, you’re always saved. One does get into Heaven because they persevere but because they are saved. 
 
The 7th Articles of Faith
Religion will not get you into Heaven. Going and attending a church or churches nonstop will not get you into Heaven. The Children of Israel were in the middle of nowhere and God proved to them over and over again who He was. Food fell from the sky daily and yet they wouldn’t believe in God.
 
Once you’ve been saved you will be a different person than what you were before. You will leave those sinful things behind because they can’t be of God, the one living inside you. Now this does not mean that a saved person can not backslide. We know of a story in the Bible of the prodigal son that left what he knew. However, he came to the end of his money and knew what he needed to do and go back home. There is something (God) that lives on the inside that is stronger than that which is on the outside (flesh).
 
Matthew 7:20-23
Many of folks just want to join the church, membership. There will be many that will say they know God but they’re not saved. They’ve created a form of god in their own mind and believe in that thinking it will get them into Heaven. Many of religion will bust Hell wide open. There have been many that they’ve made a profession of being saved. Some we have seen walk the aisle, bow at the altar, pray, cry, weep and can then tell you their testimony. Yet they show no fruit. It doesn’t matter what you’ve done, how you’ve done it or when, if you’ve not been changed on the inside then your lost.
 
Some don’t get it at all and just will not accept Christ.
 
Rocks have no depth therefor nothing will live long if it’s planted in rocks. It will quickly grow but will die the first time something is thrown it’s way. A person that just goes thru the motions of being saved.
 
The thorns will snuff out the growth. The thorns are the lusts of the world and if a person is not changed (saved) they will quickly fall back into their sinful way.
 
The seeds that flourish in the good ground are the ones that are actually saved. Rooted in good ground as to where they grow and become strong. When the storms come and the thorns of lust come around they continue to grow and are not changed by them but made stronger.
 
Many have made a profession of being saved but look around, they are missing, they are not here in attendance.
 
There are many out there that claim they are saved and yet they live like they want outside of church or church attenders. You’re living a life of a deceiver and are in great danger with God. Stating that you’re saved and never going back to church does not line up with Gods Word.
 
Colossians 1:21-23

21. And you, that were sometime alienated and enemies in your mind by wicked works, yet now hath he reconciled
22. In the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight:
23. If ye continue in the faith grounded and settled, and be not moved away from the hope of the gospel, which ye have heard, and which was preached to every creature which is under heaven; whereof I Paul am made a minister;

 
This is not about works. One could work themselves to death but you’re own works will not get you into Heaven. 
One can’t get lost after their saved, they will always know where their Father is.
