Contradiction with James 4:3
This verse explains that prayers are not granted when asked with wrong motives, unlike John 16:24, which suggests requests made in Jesus' name will be fulfilled.
James 4:3: Ye ask, and receive not, because ye ask amiss, that ye may consume [it] upon your lusts. [lusts: or, pleasures]
Contradiction with 2 Corinthians 12:8-9
Paul’s repeated prayers for relief were not granted, indicating that not all prayers in Jesus' name are answered.
2 Corinthians 12:8-9: For this thing I besought the Lord thrice, that it might depart from me.
Paradox #1
The verse encourages asking and receiving to have joy, which might seem contradictory to some teachings about being content with what one has or the idea that material possessions do not lead to true happiness. Some might see a conflict between seeking fulfillment through prayer versus finding contentment in one's current state.
