Dr. albert Mohler writes a good warrning to those evangelicals who practice hyperevangelism that wants to give premature assurance. Read his article: Guarded Through Faith: Assurance and Perseverance.
It is also important to understand that our assurance of our salvation is rooted in the eternal purposes of God, in the Son’s accomplished work, and in the sealing of the Spirit. I was greatly encouraged by his article, and I hope you will be too.
