Fear not, Daniel: for from the first day that thou didst set thine heart to understand, and to chasten thyself before thy God, thy words were heard, and I am come for thy words. But the prince of the kingdom of Persia withstood me one and twenty days (Dan. 10:12, 13).
We have wonderful teaching here on prayer, and we are shown the direct hindrance from Satan.
Daniel had fasted and prayed twenty-one days, and had a very hard time in prayer. As far as we read the narrative, it was not because Daniel was not a good man, nor because his prayer was not right; but it was because of a special attack of Satan.
The Lord started a messenger to tell Daniel that his prayer was answered the moment Daniel began to pray; but an evil angel met the good angel and wrestled with him, hindering him. There was a conflict in the heavens; and Daniel seemed to go through an agony on earth the same as that which was going on in the heavens.
"We wrestle not against flesh and blood, but against principalities, against powers… against wicked spirits in high places" (Eph. 6:12, margin).
Satan delayed the answer three full weeks. Daniel nearly succumbed, and Satan would have been glad to kill him; but God will not suffer anything to come above that we "are able to bear."
Many a Christian's prayer is hindered by Satan; but you need not fear when your prayers and faith pile up; for after a while they will be like a flood, and will not only sweep the answer through, but will also bring some new accompanying blessing.
Hell does its worst with the saints. The rarest souls have been tested with high pressures and temperatures, but Heaven will not desert them.
