The work of the Lord needs our prayers. We are taught in the Word:
Pray without ceasing.
1Th 5:17
Evening, and morning, and at noon, will I pray, and cry aloud: and he shall hear my voice.
Ps 55:17
Therefore I say unto you, What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them.
Mark 11:24
Prayer is access to the heart of God
We are assured in Mark’s gospel that prayer makes a difference. Every act of faith must rest on the promise of God. If we know that it is God's will, then we can pray with utter confidence that it will be done. In fact, we can pray with confidence on any subject as long as we are confident it is according to God's will as revealed in the Bible or by the inner witness of the Spirit. When we are living in touch with the Lord and praying in the Spirit, we can have the assurance of answered prayer before the answer actually comes.
