James 1:6

 James 1:6 But let him ask in faith, with no doubting, for the one who doubts is like a wave of the sea that is driven and tossed by the wind.

​"Nothing Doubting"
1. We are to believe without doubting. "If ye have faith, and doubt not … " (Mt 21:21). We may be tempted to doubt. We may have to pray, "Lord, I believe; help Thou mine unbelief " But we can take sides with our faith and by the exercise of it give doubt no chance to grow. Such faith moves mountains.
2. We are to pray without doubting. I will therefore that men pray every where, lifting up holy hands, without wrath and doubting" (1 Tim. 2:8). The man who lacks wisdom must ask of God "but let him ask in faith, nothing wavering" (James 1:6). The doubting man, says James, is like a storm‑driven wave of the sea and he need not expect anything of the Lord.
3. We are to obey without doubting. Peter was told to go with the men from the house of Cornelius "nothing doubting" (Acts 10:20; 11:12). When the Holy Spirit sends us on a mission we are to ask no questions. Peter had his scruples on this occasion and sometimes we have to give up well‑established objections if we are to help Cornelius.
Doubting means wavering, double‑mindedness. Without faith it is impossible to please God (Heb. 11:6). A man displeases God to the extent of his doubts. Doubt may assail you but do not pray, "Lord, I doubt; increase my faith"; pray, "Lord, I believe; help Thou mine unbelief." (Vance Havner)
