Character isn’t something you can fabricate when life is in the furnace. It is developed throughout your life. It is formed and reinforced through every thought, action and experience you go through. When you’re in a tight spot it is your true character that will come out of you.
A person truly functions out of the overflow of what is already in their heart (Luke 6:45).
Develop strong character: faithfulness, self control, kindness, gentleness, goodness, joy, love, peace, patience (Galatians 5:22-23). These will see you through life with dignity and strength no matter the furnace or the storms you pass through.
