The Scripture indicates that one of the great keys to effective and righteous prayer is our faith in God and belief in Christ Jesus. This is particularly true when we exercise both as we pray to God in faith, through belief in Christ Jesus, by the power of His Holy Spirit. We are to pray believing, without doubting – a truth taught in the epistle of James. Our prayers should be of genuine faith and wholehearted belief.
John 16:23-24
“In that day you will ask nothing of me. Truly, truly, I say to you, whatever you ask of the Father in my name, he will give it to you. Until now you have asked nothing in my name. Ask, and you will receive, that your joy may be full.”
