Sometimes our levels of understanding of who we are and what we are or why we are here can be draining if we don't put ourself into knowing that reason.
very important we know that in all that we are not living for ourself we are existing because of the purpose of the creator, if we could ask everyone we know if they choose to be born into the family they are now they will tell you they don't.
But have you asked your yourself why were you born into that family you love so much or asked the big question why was i created to be on earth? everything God created is for a purpose and no one was created without a purpose, understanding who you are and why you were created can make you reach your full potential.
According to EPHESIANS 2:10 (For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.)
Everything has purpose even on earth even down to the things we humans has created for example the cloth you are putting on right now is serving it purpose so with this understanding you will understand that everything has a purpose if there is no purpose for it it wont exist and known.
We are born to do good works to fulfil the creators purpose and give account when he returns.
