May the God of your hope so fill you with all joy and peace in believing [through the experience of your faith] that by the power of the Holy Spirit you may abound and be overflowing (bubbling over) with hope. Romans 15:13 Amplified Bible

The Power of Hope is one of the great Keys to release The Power Of God in your prayer life! Without The Power of Hope your life becomes hopeless!
A person without a prayer life is one without hope. Hope is the very Power we pray with. You have to set a vision before you to pray for. That vision is filled with a total dependence on God Almighty’s Word and Power to bring it to manifestation.

Hebrews 11:1 NOW FAITH is the assurance (the confirmation, the title deed) of the things [we] hope for, the proof of things [we] do not see and the conviction of their reality [faith perceiving as real fact what is not revealed to the senses].

When I pray I always see the end result or hope in the Spirit and keep that picture in my heart until the manifestation happens. For example if someone is sick you have to see them as healed and healthy. That hope is what The Bible calls a Fervent Prayer. Jesus Christ will never leave nor forsake you and He is always FAITHFUL to respond and answer your prayers.

Romans 11:11-12 Never lag in zeal and in earnest endeavor; be aglow and burning with the Spirit, serving the Lord. Rejoice and exult in hope; be steadfast and patient in suffering and tribulation; be constant in prayer.

Psalm 31:24 Be of good courage, And He shall strengthen your heart, All you who hope in the LORD.

Psalm 71:14 But I will hope continually, And will praise You yet more and more.

Psalm 119:114 You are my hiding place and my shield; I hope in Your word.

Proverbs 13:12  Hope deferred makes the heart sick, But when the desire comes, it is a tree of life.
