"And whatever you do, don't let go.
In Matthew 7: 7, Jesus said,
"Ask and you shall receive.
Seek and you shall find.
Knock and the door shall be opened to you."
Ask, Seek, and Knock.
Each of these words is in the aorist future perfect verb tense in the Greek, which means:
keep on asking—
keep on seeking—
keep on knocking!
After you make your petition to God, you are still not finished with all asking means.
One final step remains—the affirmation that your prayer will be answered.
Have you really prayed in faith?
Are you confident your requests lie within the will of God?
Then you need not hesitate to thank Him that He is going to answer.
When you go to the bank to cash a check, you don't hesitate to expect the funds. Why?
Because you have confidence in the one who wrote the check and the bank's ability to fund it.
You simply present your claim and expect the results.
To thank God in advance is to affirm your confidence in the forthcoming answer.
If you pray for someone who is sick, don't labor over thoughts and prayers of their sickness.
Pray and think of the health Christ gives.
When you think of one with a broken arm, don't think of the break, but pray and thank God for His healing power and the glory God will receive in their healing.
That is positive praying.
When you finish your prayer of intercession, don't get up—stay on your knees and thank God in advance that He has already answered your prayer.
Get up, go your way, and don't check up on God or make other provision in case it doesn't happen.
Believe Him -
Thank Him -
and leave it there."
