"Let us then approach God’s throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need." Hebrews 4:16
God does answer prayers! Our job is to believe that God can do exceeding abundantly above all that we ask or think (Ephesians 3:20). While He is already aware of what we stand in need of, we petition the Father because we are His children and He wants us to cast our cares on Him, because He cares for us (1 Peter 5:7).
