Continuing in the Sermon on the
Mount, Jesus said, “And when you fast . . .” (v. 16). Jesus assumed that
His disciples practiced fasting as it was expected in the Jews’ religion. “Then
the disciples of John came to him, saying, ‘Why do we and the Pharisees fast, but your disciples do not fast?’” (Matthew 9:14). This verse reveals two
things: (1) fasting was commonly practice among the Jews, but (2) the disciples
of Jesus were not following this custom. In other words, there was biblical
fasting to observe, and there was mere religious fasting to be rejected. We
have a window into this in the parable of the Pharisee and tax collector (Luke
18:9–14) where the Pharisee boasted, “I fast
twice a week; I give tithes of all that I get” (Luke 18:12). This regular ritual
fasting was nowhere commanded in the OT but was done to boast one’s “godliness”
before others. Jesus and His disciples did not observe this practice, as the
disciples of John observed. On the other hand, corporate fasting was expected
of all Jews on the Day of Atonement and at various times for personal and
national reasons, as we shall consider.
Fasting, as a spiritual
discipline is not found in the NT epistles but only in the Gospels and Acts. This
raises the question of whether it should be of concern to Christians. Praying
is unquestionably expected (1 Thessalonians 5:17); however, there is no such
command for fasting. It is my opinion that the nature of fasting takes it out
of the arena of disciplines. Jesus simply states that fasting must be private
and before the Father only (Matthew 6:17, 18).
In Acts fasting and prayer are
often intimately connected. The church at Antioch worshiped the Lord
with fasting and praying. While they were thus engaged, the Holy Spirit said, “Set
apart for me Barnabas and Saul for the work to which I have called them”
(Acts 13:2). They obeyed and “after fasting
and praying they laid their hands on them and sent them off” (v. 3). This
passage is particularly important to our understanding of this neglected
practice among the churches. The church worshiped with fasting and prayer, the
context intimating that the church was burdened to ascertain divine direction
to get the gospel that had so transformed their lives out to the rest of the world.
The book of Acts records the
infant church’s seeking to fulfill the great commission to make disciples (Matthew
28:18–20) without the guidance of the NT Scriptures. Now that we have the
complete NT, perhaps the need for dependence on the Spirit has lost its
urgency. Rather than shrug off what we have afore neglected without conviction,
this we should actively pursue because Jesus clearly said, “When you fast.”
Prayer is a work of the Spirit of
God. Spiritual warfare demands “praying at all times in the Spirit, with all prayer
and supplication” (Ephesians 6:18). Jude’s call to perseverance includes “praying
in the Holy Spirit” (Jude 20). Romans 8:26 points to our hope of future
glory with the promise that “the Spirit helps us in our weakness.” There
is no praying to the Father unless the Spirit enables. We can “pray,” but
without the Spirit our words get no attention in heaven. Fasting is the same. Some
have suggested that it is only as we are overwhelmed with burden that we simply
do not eat, but I would argue that we are not sensitive to the leading of the Spirit
to do so. Prayer and fasting must be Spirit-enabled as it was in Antioch. Our
lack of fasting ought to cause us real concern and drive us to seek God’s will
on the matter.
