All in Perseverance in Prayer

When we read scripture that tells us to rejoice always, pray without ceasing, or to give thanks in every situation, do we worry about being able to do these things? Are we concerned about becoming distracted, losing interest, or eventually becoming tired as we stand chanting, worshipping, and praying in the presence of God? Do we find ourselves failing at these things now after short periods of time and grow concerned about disappointing God, not making it to heaven, or failing miserably once we do get there? Do we worry about how long eternity lasts, and our ability to do these things faithfully forevermore? Well you are not alone, but do not fear.
