"But he said to me, 'My grace is sufficient for you, for my power is made perfect in weakness.' Therefore I will boast all the more gladly about my weaknesses, so that Christ's power may rest on me." -2 Corinthians 12:9
Each of us has a different personality, complete with its own set of weaknesses and strengths. Some of our weaknesses are natural or physiological weaknesses, such as being either more introverted or extroverted, while other weaknesses are the result of offenses from the past.
It's crucial for us to recognize the difference between these two types of weaknesses; whether it's because it's the way we're naturally wired or the result of wounding. The one can hold us captive in our hearts, (Hebrews 12:15) while the other is simply a matter of growth. Both can limit our potential. But both, with either forgiveness or openness to change can be overcome.
Consider this: An introverted person can be afraid to speak, but because of their thoughtfulness and perception, can have a lot of great things to say. A shy person who has been shut down in the past by stronger personalities needs to recognize that they too have worth and value.
A "type A" person can be more domineering, but without this direction or initiative, nothing would get done. A person like this who has been hurt will likely try to control outcomes and people. This person with resolved offense will view leadership as management of all that is God's.
A "people person" loves to hang out with others. They are the "life of the party". Sometimes though, they can care too much about what others think -- to the point of defining their standards by what helps them gain acceptance. They may be really sensitive. This person with God's perspective in mind will know that they can uphold God's standards for their lives and still bring the fun to any environment.
A laid-back or happy-go-lucky person may not be very organized, but can have a great ability to bring ease and resolution to tense situations. This person may be more predisposed to being lazy or lethargic. But when they recognize this and "go against the grain", they are able to successfully balance their lives with work and play.
Do you know your strengths and weaknesses? Knowing them is a great tool for knowing how to relate and interact with others. This allows us to develop to the fullest potential, letting God's power shine through.
