Prayer is proof

Prayer is the proof of our faith 

Prayer is the proof that we believe in God’s existence;
that He’s a personal God who is willing to listen, and act on our behalf. 
Faith is not something physical we possess, but it’s a sense of knowing, born of the Spirit,
that we are connected to an invisible God.

Faith is the working of the Holy Spirit in us, who convinces our hearts that:
Jesus Christ is our Savior,
God is our Father and creator,
and that we are becoming sanctified through the Person of the Holy Spirit
