Looking for purpose... means it is not something we already have and hold. We trek all over the globe to 'find' meaning, find self, find purpose... At a certain point we have to stop, and acknowledge, that Another holds the keys!
One scripture that I find deep and fascinating, is where Paul was preaching to the people of Athens. He states God's 'purpose' in making all mankind, in all times and seasons (including you and I, here and now!)
'God made all nations in all times and seasons... He did this so that they would seek him, reach out for him and find him.' (Acts 17:26-27)
God made us and 'purposed' us to seek God. Do you seek God? God's ultimate 'reach' towards us, was to become like us, in the form of man, Jesus Christ. In this way, God reaches out to us, to find us. Do you reach out to him, to find him? Your ultimate, spirit-filled purpose is bound to knowing Christ!
'Jesus said, 'I am the door. Anyone who comes through me will be saved.' (John 10:9)
