Although not ‘legalistic’ in the negative sense of the word, there are legal aspects to mature prayer that can be highly effective when utilised according to God’s pattern.
The Bible speaks of times where we can come and plead before God on our own or on behalf of another. Job lamented that no one was found to plead the case of mankind:
““For He is not a man, as I am,
That I may answer Him,
And that we should go to court together.
Nor is there any mediator between us,
Who may lay his hand on us both.” (Job 9:32-33 NKJV)
This is clearly a prophetic cry for the intercessory work of Christ, but again, the intercessory work is applied through intercessory prayer here and now on earth.
In intercessory prayer we stand and plead the case before God for the salvation of others on the basis of Christ’s finished work. Through Him all men were reconciled. We have a very strong basis for our intercessory petitions, and indeed God Himself invites us to come and reason with Him according to these truths:
““Come now, and let us reason together
(argue, convince, plead, daysman),”
Says the LORD,
“Though your sins are like scarlet,
They shall be as white as snow;
Though they are red like crimson,
They shall be as wool.”(Is 1:18 NKJV)
God is looking for people who know His will, and how to stand on His word, on behalf of the people He so dearly loves and died for.
Mary Alice Isleib says of this,
“That’s what we do in the work of intercessory prayer. We stand on the Word of God, speak the Word of God, take His Word into difficult and challenging situations, and it gives God something He can work with in the earth. God’s highest and best is to work with men and women in the earth. When they are basing their prayers on the law of His Word, He has obligated Himself to honour His Word.”
