As I have often said, the best defense is a good offense. And instead of trying to just hold our ground as Christians, we should gain ground. We should move forward. We should tell others about Christ.
When you identify yourself as a Christian, that is a good way to make yourself accountable, even to nonbelievers. By saying in your workplace (without being obnoxious), "I am a Christian," by saying to members of your family or in your neighborhood or among your friends, "I am a follower of Jesus," you are putting that stake in the ground, and they will be watching you and evaluating you.
And frankly, they will be evaluating God, too. They are will be thinking, So that is how a Christian acts. That is how a Christian treats his wife. That is how a Christian treats her husband. I get it. That is how a Christian raises their child. That is how a Christian does thus and so. . . .
They will be watching you. And nothing is worse than getting your behavior corrected by a nonbeliever, especially when they are right.
Has that ever happened to you? You did something inconsistent, and your non-Christian friend said, "I thought you were a Christian."
"Well, I am, praise God!"
"Then why did you just do that?"
Maybe you should just say it was because you sinned and then thank them for calling you on it.
When a believer is walking in fellowship with God, he or she will want to tell others about Christ.
Everyone has a testimony, which simply is their story. You don't have to go through adversity to have a testimony. What would people say about you? You have a testimony. The question is whether it is a good one or a poor one.
