Now if any of you lacks wisdom, he should ask God, who gives to all generously and without criticizing, and it will be given to him. But let him ask in faith without doubting. For the doubter is like the surging sea, driven and tossed by the wind. - James 1:5-6 HSCB
Whenever you are plagued by doubts, seek God's presence. Then you may rest assured that in time, God will calm your fears, answer your prayers and restore your confidence.
