Why prayerlessness is sin:

1. It does those around you a disservice (1 Samuel 12:23).
2. It is disobedience (Luke 18:1, 1Thess. 5:17, 1 Timothy 2:8, Matthew 6:6).
3. It reveals our unwillingness to allow God to work in our life (Luke 22:41-44).
4. It is negligence of a divine privilege purchased at a great price (Hebrews 4:14 - 16).
5. It demonstrates our independence (John 15:5, Philippians 4:13).
6. It reveals our unbelief ( Romans 10:14a, Hebrews 11:6).
7. It leaves the door open for other sins (Luke 22:40, Mark 14:38, Matthew 6:13 & 26:41).
8. It hinders revival & God's blessings ( Acts 1:14 & 3:1, Mark 1:35, 2 Chronicles 7:1-4, Jeremiah 29:11, Romans 11:22).
9. It proves God isn't first in our life   (Matthew 6:22, 24 & 33, 1 John 5:21, James 4:2-5).
