Good character is not formed in a week or a month. It is created little by little, day by day. Protracted and patient effort is needed to develop good character.
Build your character bit by bit in kind words and deeds. Make sure it is honest and comes from your heart. Use Jesus as your guide and let others see Him through your character.
Therefore, as God’s chosen people, holy and dearly loved, clothe yourselves with compassion, kindness, humility, gentleness and patience.
