Reading New Testament Through Once A Month
You can read your New Testament through once a month with about a hour reading each day. Split it between two half hour readings. start in Matthew for first half hour and First Corinthians for second half hour. If you read each day you can usual read it once a month. If you miss you need to make up the time because it will put you behind.
If you are not able to spend that much time reading I suggest you take at least 15 minutes in the morning a read some. Start in Psalm and Proverbs them go to New Testament.
I feel it is important you read your Bible every day and so try to at least read 15 minutes. I also recommend praying before you go to sleep and I do hope you will read your Bible and pray more.
