Cognate: 2480 isxýō – properly, embodied strength that "gets into the fray" (action), i.e. engaging the resistance. For the believer, 2480 (isxýō) refers to the Lord strengthening them with combative, confrontive force to achieve all He gives faith for. That is, facing necessary resistance that brings what the Lord defines is success (His victory, cf. 1 Jn 5:4). Accordingly, faith (4102 /pístis) and 2480 (isxýō) are directly connected (Js 5:16). See 2479 (isxys).

Js 5:15,16 (Gk text): "15And the prayer characterized by faith (4102 /pístis) will restore the one who is sick, and the Lord will raise him up. If he has committed sins with present effects, it will be forgiven him. 16Therefore, openly confess these sins to one another, and pray for the benefit of one another, for the purpose of being supernaturally healed. Very combative (engaging, overcoming, 2480 /isxýō) is the specific (urgent) request of a divinely-approved person who is energized (by God)."

[Here the believer seeks to make petitions (1162 /déēsis) in faith – i.e. which are in accord with God's inbirthings (the persuasion of His will).]
