And he spake a parable unto them to this end, that men ought always to pray, and not to faint;
Luke 18:1

When it comes to the benefit of continued prayer, James the Apostle establishes:

“…The effectual fervent prayer of a righteous man availeth much.” James 5:16b.

The Greek word translated ‘availeth’ is elsewhere translated prevails.

In Acts 19:20, it is translated ‘prevailed’

“So mightily grew the word of God and prevailed”.
Acts 19:20

So what does it mean for fervent prayer to ‘avail’? It simply means it prevails.

When we continue in prayer, we prevail. Praise God!

The amplified version renders the text this way: “The earnest (heartfelt, continued) prayer of a righteous man makes tremendous power available [dynamic in its working]”
James 5:16b AMP

Stop seeing prayer as something you do to fulfil all righteousness. Learn to expect results when you pray.

As the Lord Jesus prayed at Gethsemane, he took breaks but he continued praying on the same subject thrice. Learn to give matters continued attention in prayer.

If you had only thirty minutes to pray in the morning, you can adjourn and continue during your break time at work. If that still wasn’t enough, you adjourn again to continue when you get home.

When do you stop? When you win! Continued prayer prevails.
