Matthew 28:19-20That wasn't just spoken to the disciples . . . it's for us, too! He has promised to be with us -- on the job, at the store, soothing that baby, talking to that neighbor . . . you'll not be alone as you try to speak a word for Him.
Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:  Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world.
These are verses that reinforce that thought -- He will be with you; He has promised His presence as you go about your day:
The Lord replied, “My Presence will go with you, and I will give you rest.” (Exodus 33:14)
(Romans 8:38-39) For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.
As we pray, we can boldly claim that promise, and then be ready to speak . . . where? Check out these verses:
30 For two whole years Paul stayed there in his own rented house and welcomed all who came to see him. 31 He proclaimed the kingdom of God and taught about the Lord Jesus Christ—with all boldness and without hindrance!
Acts 17:17 17 So he reasoned in the synagogue with both Jews and God-fearing Greeks, as well as in the marketplace day by day with those who happened to be there.
I hope you will have time today to look up these verses, too:
We can share our faith in our car, as Phillip did in a chariot: Acts 8: 29-35.
We can share our faith in a boat, as Paul did: Acts 27: 22-25.
You may know people who share in prisons, as we see Paul doing, even though he was one of the prisoners: Phil. 1: 12-13
There are no limits as to where we can graciously speak a word for Him!
