“And the child grew, and waxed strong in spirit, and was in the deserts till the day of his shewing unto Israel.”
Luke 1:80

The Bible tells us about John that he waxed strong in spirit, and what’s more important to God in your walk with him is the state of your spirit, it is your spirit that he ministers to:
“And the Spirit himself speaks to our spirits…” Romans 8:16, ERV
And one thing we knew John did was that he fasted and prayed often and taught his disciples the same:
“Then the followers of John came to Jesus and said, “We and the Pharisees fast often…” Matthew 9:14
The Bible tells us that Jesus before he began his ministry took out time to fast and pray for forty days: Matthew 4:2
We are also told how the early church took out time to fast and pray before sending forth the Apostles Paul and Barnabas: Acts 13:3.
In the time of preparation, you ought to take out time to fast and pray and strengthen your spirit.
“And Jesus said unto them… the days will come, when the bridegroom shall be taken from them, and then shall they fast.” Matthew 9:15
