In Revelation Jesus said, "I know your works, your labor, your patience, and that you cannot bear those who are evil. And you have tested those who say they are apostles and are not, and have found them liars; and you have persevered and have patience, and have labored for My name's sake and have not become weary. Nevertheless I have this against you, Rev 2:2-4 (NKJV)
Jesus made sure others knew he saw the good in them before he told them about their deficiencies. We all need to follow his example.
