People today are often trying to discover who they are or why they're here. Allow me to shed a little light on this subject from Ephesians One (The Message).
"Long before he laid down earth's foundations, he had us in mind, had settled on us as the focus of his love ... It's in Christ that we find out who we are and what we are living for. Long before we first heard of Christ and got our hopes up, he had his eye on us, had designs on us for glorious living, part of the overall purpose he is working out in everything and everyone."
If we try to find purpose and meaning through the things of this world, we will never be satisfied. Temporary contentment may occur but not lasting.
The scripture above states that we find who we are in Christ - a Christian, a follower of Christ. We also find what we are living for in Christ - to be Christ-like. The Lord knows exactly how we were put together with our gifts and abilities, and He knows how He planned for us to use them. He desires for us to chose His will, so we can experience fulfillment in our lives.
If we're searching for meaning and purpose, we must shift our focus from the world to the Creator of the world. When He created the earth, He thought of us. He loved us from the beginning and wants the best for us now.
