Jesus has been exalted to sit at the Father's right side in heaven. By the power of the Father, He rose from the dead to work with the Father on Their plan to complete the creation of mankind in God's image. No plan of Theirs has ever failed by even the smallest degree. Yet few use their faith in Jesus' work. Most make no effort to seek His help in producing the fruit that glorifies God.
Conclusion: Humanity shows it cannot be bothered with such a triviality as prayer.
