James 1:2-8 (New International Version, ©2011)
2 Consider it pure joy, my brothers and sisters,[a] whenever you face trials of many kinds, 3 because you know that the testing of your faith produces perseverance. 4 Let perseverance finish its work so that you may be mature and complete, not lacking anything. 5 If any of you lacks wisdom, you should ask God, who gives generously to all without finding fault, and it will be given to you. 6 But when you ask, you must believe and not doubt, because the one who doubts is like a wave of the sea, blown and tossed by the wind. 7 That person should not expect to receive anything from the Lord. 8 Such a person is double-minded and unstable in all they do.
Matthew 21:22 (Amplified Bible)
22And whatever you ask for in prayer, having faith and [really] believing, you will receive.
2 Corinthians 5:7 (New International Version, ©2011)
7 For we live by faith, not by sight.
Hebrews 11:1-2 (New Living Translation)
1 Faith is the confidence that what we hope for will actually happen; it gives us assurance about things we cannot see. 2 Through their faith, the people in days of old earned a good reputation.
Matthew 7:7-8 (New International Version, ©2011)
7 “Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. 8 For everyone who asks receives; the one who seeks finds; and to the one who knocks, the door will be opened.
