I can tell many anecdotes of my life that God changed .... But this goes beyond just thinking about whether God will do something.
God works in many ways and uses even what you least imagine to bless your life to travel from someone.
You will wonder ... Why am I going to believe in God ..?
I would tell you ... If you only knew what God does when you believe him in what he will do in you ... You were already talking about how wonderful he is.
He is a father and as such he wants to guide you and teach us which way to choose and how to focus at a time of great price for us as children of God.
Faith is something so powerful that believing that you will be healed or that you are free from all evil ... It is already done if you have faith and ask the father for the heart.
Let God enter your heart and act on faith through his love and glory.
