Identity crisis simply means a feeling of uncertainty about who you really are and what your purpose in life is. An example of someone who may have had an identity crisis in the Bible is Moses (although this is not recorded).
Exodus 2:10-11 tell us that he grew up as a Son to Pharaoh's daughter, in the Palace, learning and internalizing all the ideologies of being a Prince. His mannerisms and comportments may not have been different from that of a Prince. He may have had certain rights and privileges to enjoy. Although all of these happened to Moses, he never lost sight of who he really was. As we could evidently see later on in his life, he tried to identify with his own brothers by killing an Egyptian for their sake.
Jesus Christ asked His disciples; "Whom do men say that I the Son of man am?" (Matthew 16:13-17 KJV). The striking thing is there was no uniformity in all they said. This means that when you allow any other source (apart from the Word) to define you, all you will get are varying opinions. In the end, only Peter gave the correct and required answer and that by the Spirit of God.
Some of us have lost sense of our identity. We have allowed people around us (friends, family and fans) to define us. Some people are born into royalty and they see themselves as such, some into slavery, some into wealth et cetera and all have acted in accordance to the acceptable norms and values of such settings.
There is a danger in allowing people or your social environment to define who you are. Human beings are not stable in their ways, their minds and their judgments. They give you a particular attribute today and tomorrow they give you another. This is why the Bible warns us not to put our trust in man.
It is better to trust in the LORD than to put confidence in man. Psalm 118:8 KJV
Man can never give an accurate description of who you really are because he did not create you. Only the Ancient of days, the One who knew you before you were formed and made you with His own hands can accurately describe you and guess what!- His judgment is forever the same, He will never change His mind on whatever He says you are. His word can never fall, fail nor falter, for Jesus does not change—yesterday, today, tomorrow, he is always totally himself.(Hebrews 13:8)
The question therefore is 'Who am I?' Never try to avoid this question. If you do not answer it soon enough, the devil will tell you lies about it. Circumstances of life will ask you this same question, as it did the seven sons of Sceva, "Jesus I know, and Paul I know; but who are ye?" (Acts 19:15 KJV) I bet you do not want to wait until then.
The definition of who you are is not far-fetched. It is right there in the Word. You are a new Creation.
Because of this decision we don't evaluate people by what they have or how they look. We looked at the Messiah that way once and got it all wrong, as you know. We certainly don't look at him that way anymore. Now we look inside, and what we see is that anyone united with the Messiah gets a fresh start, is created new. The old life is gone; a new life burgeons! Look at it! (2Corinthians 5:17 The Message)
Because of this, there are certain things that have been made available to you, God labeled you with them (as your identity) and they are called New Creation Realities'.
One lesson you must learn at this point is; do not allow anyone to define you. You true identity lies in the Word of God. On the physical, it may not look like it but the Word of God is ever true. It takes faith to walk in all that we have been given through it.
that's why we live with such good cheer. You won't see us drooping our heads or dragging our feet! Cramped conditions here don't get us down. They only remind us of the spacious living conditions ahead. It's what we trust in but don't yet see that keeps us going. ( 2Corinthians 5:6-8 The Message)
Always give thanks to God because He alone has designed your Identity Card and has put it in the Bible. He also promised that He will never alter anything in it forever – not your ever superior position, not your status. Hallelujah!
