1 Thessalonians 2:11-12

Now may our God and Father Himself, and Jesus our Lord guide our steps to you (by removing the obstacles that stand in our way). And may the Lord cause you to increase and excel and overflow in love for one another, and for all people, just as we also do for you. 

Paul faced obstacles in getting to the believers of His time.  We may also encounter obstacles reaching out to fellow believers and non-believers.  Jesus is the remover of those obstacles.  He knows what we face and how to overcome it.  The Lord will cause our love to grow for each other and any barriers to be removed.
