When one is saved, the devil will try to put doubts in their mind about their salvation but be rest assured that he will not succeed in taking you out from God's hand. If you know you are saved, rebuke the doubt "Submit yourselves therefore to God. Resist the devil, and he will flee from you" (James 4:7). If you aren’t talk to God, ask Him if there is any unrepented sin and ask for forgiveness, then believe that you have been forgiven. The Holy Spirit bears witness of our salvation-He gives us the assurance that we are right with God "For all who are being led by the Spirit of God, these are sons of God... The Spirit Himself bears witness with our spirit that we are children of God." (Romans 8:14,16). If you obey the commandments of God, do not work according to the flesh but allow the Spirit to lead you, He will bear witness in your heart that you are on the right tract.
