'Effective' in the Bible

for a wide door for effective service has opened to me, and there are many adversaries.

But if we are afflicted, it is for your comfort and salvation; or if we are comforted, it is for your comfort, which is effective in the patient enduring of the same sufferings which we also suffer;

and I pray that the fellowship of your faith may become effective through the knowledge of every good thing which is in you for Christ’s sake.

Therefore, confess your sins to one another, and pray for one another so that you may be healed. The effective prayer of a righteous man can accomplish much.
