“For the earnest expectation of the creature waiteth for the manifestation of the sons of God.”  
Romans 8:19

The world is waiting for you!
Once you got born again, you became ‘the expected’. You are expected to grow and bring others into the same liberty you enjoy. The good news is, every creation is waiting for you, including that unbeliever in your office or neighbourhood.
“For the creature was made subject to vanity, not willingly, but by reason of him who hath subjected the same in hope,”  Romans 8:20
The one without the life of God is subject to vanity- and he knows. This is why you have people searching for one adventure or the other, why they indulge harmful substances or experiences just to fulfill the expectation of their hearts- to do something worthwhile on the earth and give themselves a sense of fulfillment.
“In hope of eternal life, which God, that cannot lie, promised before the world began;”  Titus 1:2
It is God that subjected them and gave them hope; the hope of eternal life, but their ignorance have made them wonder off, that is until you show up with what they’ve always wanted- the glorious goodness of salvation and life in Christ.
Never mind if they mock or insult you at first, never mind if they look more naturally accomplished than you, know this- you have the life they so seek and be bold enough to tell them, just like Paul was:
“And Paul said, I would to God, that not only thou, but also all that hear me this day, were both almost, and altogether such as I am, except these bonds.”  Acts 26:29
That unbeliever is waiting for you; God has caused him to expect you- go preach!
