James 1:6

“But let him ask in faith, etc.] Not only in the faith of the divine Being that God is; but in the faith of the promises he has made; and in the faith of his power and faithfulness to perform them; and in the faith of this, that whatever is asked, according to the will of God, and is for his glory, and his people's good, shall be given. Nothing wavering; about the thing asked for, whether it is right or no to ask for it; for that should be settled before it is asked for; nor about the power of God to do it; nor about his will, in things he has declared he will do; nor about his faithfulness to his promises; nor at all questioning but what is proper, suitable, and convenient, will be given in…”

“ask in faith--that is, the persuasion that God can and will give. James begins and ends with faith. In the middle of the Epistle he removes the hindrances to faith and shows its true character [BENGEL]. wavering--between belief and unbelief. Compare the case of the Israelites, who seemed to partly believe in God's power, but leaned more to unbelief by "limiting" it. On the other hand, compare Act 10:20; Rom 4:20 ("staggered not . . . through unbelief," literally, as here, "wavered not"); Ti1 2:8. like a wave of the sea-- Isa 57:20; Eph 4:14, where the same Greek word occurs for "tossed to and fro," as is here translated, "driven with the wind." driven with the wind--from without.…”

“But let him ask in faith - See the passages referred to in James 1:5. Compare the Matthew 7:7 note, and Hebrews 11:6 note. We cannot hope to obtain any favor from God if there is not faith; and where, as in regard to the wisdom necessary to guide us, we are sure that it is in accordance with his will to grant it to us, we may come to him with the utmost confidence, the most entire assurance, that it will be granted. In this case, we should come to God without a doubt that, if we ask with a proper spirit, the very thing that we ask will be bestowed on us. We cannot in all other cases be so sure that what we ask will be for our good, or that it will be in accordance with his will to bestow it;…”

“But let him ask in faith - A firm confidence in God. St. James also both begins and ends with faith, Jam 5:15; the hinderances of which he removes in the middle part of his epistle. He that doubteth is like a wave of the sea - Yea, such are all who have not asked and obtained wisdom. Driven with the wind - From without. And tossed - From within, by his own unstableness. James 1:8”

“1:6 Do not waver, for a person with divided loyalty: The Greek is often translated “Do not doubt, for a person who doubts,” but the sense here is of a person whose loyalty is divided between God and the world (see 1:8).”

“let: Mat 21:22; Mar 11:22-24; Ti1 2:8; Heb 11:6 he: Gen 49:4; Eph 4:14; Heb 10:23, Heb 13:9; Pe2 2:17; Jde 1:12, Jde 1:13 James 1:7”
