Perseverance, determination, and intensity.
It begins with the refusal to readily accept denial.
This develops into a determination to persevere, to spare no time or trouble, until an answer comes.
This grows in intensity until the whole being is given to God in supplication.
Boldness comes to lay hold of God’s strength.
At one time it is quiet; at another, bold.
At one point it waits in patience, but at another, it claims at once what it desires.
In whatever shape, persistence always means and knows that God hears prayer; I must be heard.
