4. Fasting is the expression of desperation to God and the amplification of desire (Jer. 29:13)

Jeremiah 29:13

[13]And ye shall seek me, and find me, when ye shall search for me with all your heart.

Psalms 63:1-3

[1]O God, thou art my God; early will I seek thee: my soul thirsteth for thee, my flesh longeth for thee in a dry and thirsty land, where no water is;

[2]To see thy power and thy glory, so as I have seen thee in the sanctuary.

[3]Because thy lovingkindness is better than life, my lips shall praise thee.

God will never turn away or turn down the prayer of the desperate

Psalms 102:17

[17]He will regard the prayer of the destitute, and not despise their prayer.

James 5:17-18

[17]Elias was a man subject to like passions as we are, and he prayed earnestly that it might not rain: and it rained not on the earth by the space of three years and six months.

[18]And he prayed again, and the heaven gave rain, and the earth brought forth her fruit.
