Treat every person you meet like a real person. Look at them. Give them a kind smile. Listen.  Be present for the other person, not just yourself.  One way we love the God we cannot see is by loving the people we can see.  When we do this there is a sense in which both persons experience a divine encounter, one in which God is involved.  God wants to embrace someone today, but He needs your arms.

“Beloved, let us love one another, for love is from God; and everyone who loves is born of God and knows God. The one who does not love does not know God, for God is love.  By this the love of God was manifested in us, that God has sent His only begotten Son into the world so that we might live through Him.  In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins.  Beloved, if God so loved us, we also ought to love one another.  No one has seen God at any time; if we love one another, God abides in us, and His love is perfected in us.  1 John 4:7-12 (NASB)
