This involves the heart as opposed to outward appearance
(Matthew 6:16-18); the physical "pouring out of water" was likened to the
spiritual "pouring out of the heart" (Lamentations 2:19) during a time of fasting (I Samuel 7:6)
For us who know the "exceeding wealth of His grace"
in Christ Jesus (Ephesians 2:6-7), God's will for us in Christ Jesus (I Thessalonians 5:17-18) is that our communion with Him be a time of petition accompanied with
thanksgiving (Philippians 4:6-7)
