One of my favorite passages of scripture is Hebrews 4:16: "Let us then approach the throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need." I use these words several times a week when I'm visiting people and praying for people. I find such comfort and hope in them.
Its a great reminder that we can approach God in prayer knowing that He hears us and is willing to act on our behalf. It's also interesting that the promise is not deliverance from whatever is happening, but the offer of mercy and grace to help us during our time of need. God never promises to deliver us from our circumstances (even though sometimes He does) but he does promise to deliver us through our circumstances.
May you pray with conviction that God sits on His throne of grace to act on your behalf.
