Why should Christians pray in faith?

Prayer is fundamentally an exercise of faith, as emphasized in Hebrews 11:6, which states, 'But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him.' When Christians pray with sincere belief in God’s character and promises, they acknowledge their dependence on Him. This faith not only pleases God but also strengthens the believer’s resolve in prayer. As such, faith informs the posture of prayer, encouraging believers to approach God with confidence, even amidst uncertainty or challenges.
