One way to share your faith is to post images on your Facebook page with scripture. Here is one I created and used on my page. Freely use it and pass it on to your friends.
Job 5:9-11 (NKJV)
Who does great things, and unsearchable, Marvelous things without number. He gives rain on the earth, And sends waters on the fields. He sets on high those who are lowly, And those who mourn are lifted to safety.
