How does someone get Saved?
How do you know you are Saved?
How do you know you will go to heaven?
I will tell you, that when you make the decision to repent and ask Jesus to make you clean, we feel new. At first, it can be easy to turn away from sin because often there is a fire that burns so brightly in us. Yet, we don't understand God the way that we need to in order to keep that fire burning.
Some people here will argue because none of us know everything about the creator of, well, everything...
Salvation doesnt mean you arent ever going to have hard times and suffer. Quite the opposite. You will...but the beauty is in having faith and trust that God is going to teach you through it all to strengthen you. This is called justification. If you begin to feel darkness creep in and your joy begin to fade, there are a few things that can keep this from happening or reverse it.
#1 Find quiet time to talk to God. Just you and Him every day.
#2 Make the time to read your Bible every single day.
#3 Try to get as much of the world out of your life as you can. Wordly music, television, etc. and fill it with Christian music and inspirational blessings.
#4 Find a church and find something to do in that church and beyond it's walls to help others.
#5 Rebuke the devil in Jesus' name and he will flee from you.
Remember that God loves us, even when we mess up, but once He begins a work in you, He will see it finished! God's promises are true...and if you don't know what promises He has made to us in the Bible, that's what I would read first! He has never lied and you can stand on His truth!
