James advised Christians to pray whenever they are in
difficulties. While praying, they must give thanks to God. When any Christian
has occasion to rejoice, he should sing praises to God. James admonishes
Christians to confess their sins and pray for one another, since the serious
prayer of a good man works miracles.
Factors which may hinder the effectiveness of prayer are: 
  • Lack
    of concentration.
  •  Lack of faith 
  • The order or arrangement of prayer which must include thanksgiving, confession of sins, etc. 
  • Sin.
