To be honest, I have felt uncertainty surrounding my own salvation for years. Some moments more assured and other moments not as much. I have received Jesus and my hope is in him.
Great.
From my 35 years of being saved i would strongly recommend you read the Gospel of John right now.
Take notes everytime you come across the mention of the Holy Spirit.
This is the MOST IMPORTANT BLESSING GOD has for you (us) after recieving Christ in your heart.
In Christianity, nothing is greater or more important for your walk with Christ then the Holy Spirit.
Pray as you read the Gospel of John.
But you, when you pray, go into your room, and when you have shut your door, pray to your Father who
is in the secret
place; and your Father who sees in secret will reward you openly. Matthew 6:6
