Ye are my witnesses...
Isaiah 43:10a says, "Ye are my witnesses, saith the LORD, and my servant whom I have chosen...".
We are His witnesses! We are told in Matthew 28, "Go Ye...".
We're told to "be ready" in 1 Peter 3:15. It says, "But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear:"
We're told to "Let your speech be alway with grace, seasoned with salt, that ye may know how ye ought to answer every man" in Colossians 4:6.
Food for thought from the apostle Paul...
For though I be free from all men, yet have I made myself servant unto all, that I might gain the more. And unto the Jews I became as a Jew, that I might gain the Jews; to them that are under the law, as under the law, that I might gain them that are under the law; To them that are without law, as without law, (being not without law to God, but under the law to Christ,) that I might gain them that are without law. To the weak became I as weak, that I might gain the weak: I am made all things to all men, that I might by all means save some. And this I do for the gospel's sake, that I might be partaker thereof with you. Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain. And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible. 1 Corinthians 9:19-25
Here's our example...
2 And Paul, as his manner was, went in unto them, and three sabbath days reasoned with them out of the scriptures,
3 Opening and alleging, that Christ must needs have suffered, and risen again from the dead; and that this Jesus, whom I preach unto you, is Christ.
4 And some of them believed, and consorted with Paul and Silas; and of the devout Greeks a great multitude, and of the chief women not a few.
5 But the Jews which believed not, moved with envy, took unto them certain lewd fellows of the baser sort, and gathered a company, and set all the city on an uproar, and assaulted the house of Jason, and sought to bring them out to the people.
6 And when they found them not, they drew Jason and certain brethren unto the rulers of the city, crying, These that have turned the world upside down are come hither also;
