Ephesians 4:31,32 (KJV)
31 Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice:
32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you.
How can Christians hold grudges against people and still expect forgiveness from God? This goes against our desire to be forgiven.
