2 Corinthians 4:13-14

It is written: "I believed; therefore I have spoken." (Psalm 116:10) With that same spirit of faith we also believe and therefore speak, because we know that the one who raised the Lord Jesus from the dead will also raise us with Jesus and present us with you in His presence.

For a long time I believed myself a christian, but seldom if ever acknowledged it with my words or my interactions with other people, whether they be close friends or complete strangers.

Here, the apostle Paul quotes Psalm 116:10 in saying that if you truly believe, God's name would be constantly on your lips.  You would proclaim Him even in the mundane, because to do so is to obey the Lord's command.

Over and over again, the bible teaches to "love one another." (John 13:34; Romans 12:10, 13:8; Galatians 5:13; Ephesians 4:2; 1 Peter 1:22, 3:8, 5:14; 1 John 3:1, 3:23, 4:7, 4:11; 2 John 1:5)  What greater love is there than to share the gospel with your fellow man?  There is none better.

The word of God brings life.  At best, everything else will die with the world.  At worst, it will distract you from Christ as the focus and kill you.

You might be thinking to yourself, "There's no way I (the failure, the idiot, the sinner) am qualified to bring this message to others.  Wouldn't God want someone better to tell these people the gospel?  Doesn't He know that I'll screw it up?"

Jump back a few verses to 2 Corinthians 4:6-7.  "For God, who said, "Let light shine out of darkness," made His light shine in our hearts to give us the light of the knowledge of the glory of God in the face of Christ.  But we have this treasure in jars of clay to show that this all-surpassing power is from God and not from us."

You're right!  Your are nowhere near qualified, but He made you as a "jar of clay," the most plain, ordinary, average, fragile, replaceable vessel there was, on purpose!  You telling people about Jesus has nothing to do with you!  Obviously, you're there, but that's about the extent of your involvement in the transformation of a person's life.  God calls us to love people by telling them about Jesus not so that we'll change their lives (only He can do that), but so that we might be changed.  Your willingness to tell people about something is a great indicator of your own faith in that thing.

It's not normal to talk to strangers.  We drill that into our children's heads over and over and over.  "Don't talk to strangers!"  God is calling us to the exact opposite; "Talk to strangers!"  Do it.  It's awesome.
