Hope is defined as: To desire with expectation of fulfillment. If our hope is to spend eternity with God, and He has promised this to us, we can expect our hope to be fulfilled.
Faithful is defined as: Firm in adherence to promises. To be faithful in prayer is to be constantly in conversation with God, praising Him, professing our love for Him, and thanking Him for our many blessings and promises.
Be joyful in hope, patient in affliction, faithful in prayer. Romans 12:12
