Psalm5:3 My voice shalt thou hear in the morning, O Lord; in the morning will I direct my prayer unto thee, and will look up
DISCOVER YOURSELF
When I was in school as an undergraduate, I don't read at midnight. I discovered that once I sleep at night, I don't wake up till the next morning. Some people have the grace to sleep and wake up at midnight to read but I don't. If I try it, i'll walk around all day like a drunk.
Having known that, I rescheduled my reading time and drew a plan for my active hours. I could read from afternoon till midnight as long as there's no nap in between. I discovered my body's requirement for sleep is minimum of 6 hours a day.
You may be wondering how this story relates to prayer. Before you can have a consistent prayer life, you must discover yourself especially your body's requirement for rest and your active time. Some are natural early risers while others are late risers.
Many years ago, I tried praying between 1-3pm at night but it wasn't working for me because i'm active till about 12 midnight and i'm expected to wake up between 5-6am in the morning. I was damaging my health because I wasn't getting enough sleep so I stopped. My prayer life became better when I discovered myself and struck a balance between work time, resting time and waking time.
Also, you must take your time to know what your daily schedule is. No matter how busy you are, there's a time that can be carved out for prayer. If you form the habit of sleeping early, waking early to pray will not be a problem.
However, for those that return home very late at night and leave home early in the morning time, it may not be possible to pray well in the morning but you can take advantage of break time in the office or the hours before work starts to commune with your heavenly father.
What matters most is not the length of hours spent in prayer but the quality of fellowship and consistency.
Father, I cast out the spirit of prayerlessness in my life. Holy Spirit, baptize me afresh with the Spirit of prayer.
