Being Bold in a natural sense has its advantages. When others fail to complete a task, the person or persons possessing this quality can push through till the job is accomplished. However when there are hostile forces arrayed against a certain endeavor, even the boldest of men can fall short of executing a task.
But when faithful men and women unite in prayer calling on the a Lord, his Grace will role in on the scene and supercharge the saints with a Boldness that will not be denied. It takes faith to access this kind of Grace.
Acts 4:29-31
29 And now, Lord, behold their threatenings: and grant unto thy servants, that with all boldness they may speak thy word,
30 By stretching forth thine hand to heal; and that signs and wonders may be done by the name of thy holy child Jesus.
31 And when they had prayed, the place was shaken where they were assembled together; and they were all filled with the Holy Ghost, and they spake the word of God with boldness.
