Be the person that isn't looking to use someone. Take the time to get to know them, look beyond the surface.
For many of us our struggles and triumphs are internal rather that external. Get to know their inner life, whats deepest within them. If you recognize an inner tribulation or inner tranquility, don't exploit them, but give them words of encouragement and confirm them.
Be a friend.
In doing so you might help them to continue on or persevere.
In John 15:13-16, Jesus empowers his followers by giving them words encouragement and confirmation. He no longer calls his followers servants, but friends.
He encourages and confirms their inner life by uniting with them to the covenant of friendship which moves them to the deeper covenant purposes of God.
Jesus gives his friends purpose, dignity, and meaning to the glory of God.
Eugene Peterson in his book "Leap Over A Wall" states,
"Evil doesn't stand a chance against goodness... Hostility is picayune compared to friendship."
When we take the time to look beyond the surface of a person, we demonstrate God's goodness, love, and friendship to them—and in so doing it renders evil powerless and incapable.
Look beyond the surface and be a friend.
