It is the Holy Spirit who awakens us to our need, and then intercedes for us to secure the will of God with reference to our need. The Holy Spirit also enables believers to exercise the graces of humility, faith, love and hope, so that our prayers will be more than just fleshly whinings. Perseverance implies opposition. The world, your flesh, and the devil, oppose your prayers and constantly conspire to try to make you give up praying. You and I must to pray with the conviction that God loves to give good gifts to His children, and with the confident expectation that He will surely give us what is best, when it is best.
Prayer is the exercise of faith.
So if you have quit praying, it is because you have already quit believing. One of the best ways that you can demonstrate your love for others is to faithfully pray for them. You should regularly pray for all the people of God, because they belong to God by adoption, they belong to Christ by redemption, and because we are all members one of another. Pray for the unity, purity and prosperity of all those who love and fear the Lord.
