So why is this your final question?
I don’t have words that can convince anyone. I cannot give you the gift of faith, only God can do that. If you quiet yourself and pray, and ask in a humble way, not demanding, not arrogantly, ask God to reveal himself to you. Ask the next day and the next day. Ask him to touch your heart.
There are people through the centuries who have given their life to God. The reason is that his love, his kindness, was so amazing to them, they gave up everything to follow him. Christ is the pearl of great price, that when you find it, you sell everything to purchase that pearl. This grace I wish for you.
