'Effective' in the Bible

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;

but He has said to me, “My grace is sufficient for you [My lovingkindness and My mercy are more than enough—always available—regardless of the situation]; for [My] power is being perfected [and is completed and shows itself most effectively] in [your] weakness.” Therefore, I will all the more gladly boast in my weaknesses, so that the power of Christ [may completely enfold me and] may dwell in me.
