1. Consider carefully the definition of faith: a) a belief in the actual existence of the living God, and b) placing a trust in His words and engendering an obedience to them. How does this affect your understanding of "ask in faith?" What impact does doubt have here? What do you observe of its impact to a doubting Believer's life?

For there is one God and one Mediator between God and men, the Man Christ Jesus, who gave Himself a ransom for all, to be testified in due time, for which I was appointed a preacher and an apostle — I am speaking the truth in Christ and not lying — a teacher of the Gentiles in faith and truth. I desire therefore that the men pray everywhere, lifting up holy hands, without wrath and doubting; (1 Tim 2:5-8, NKJV)

If any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach, and it will be given to him. But let him ask in faith, with no doubting, for he who doubts is like a wave of the sea driven and tossed by the wind. For let not that man suppose that he will receive anything from the Lord; he is a double-minded man, unstable in all his ways. (Jas 1:5-8, NKJV)

2. Consider how a discussion about doubt explores the meaning of the power of prayer. How did Jesus do what was done to the fig tree? What was He teaching?

So Jesus answered and said to them, "Assuredly, I say to you, if you have faith and do not doubt, you will not only do what was done to the fig tree, but also if you say to this mountain, 'Be removed and be cast into the sea,' it will be done. And whatever things you ask in prayer, believing, you will receive." (Matt 21:21-22; Mark 11:22-24, NKJV)
