Growing in Faith
I do agree that if you are saved your good actions, being produced by the Holy Spirit dwelling in you, will serve as a testimony for others, of how God works in your live. But the bible clearly teach us that faith comes trough hearing and hearing the word of God.

The Way of the Master
In the lower left corner you are going to see a link to a video with the name "Hell's best kept secret" don't be scared by the name (it is not a turn or burn message), please watch that video. I hope that it will be as revealing for you as it was to me when I first saw it. Don't check all the other excellent resources on evangelism before watching the video.
Numbers 6:24-26 to you!
