A Testimony of
Jesus Christ

You understand your testimony of Jesus Christ. How does it compare to this testimony of Jesus Christ? "And I, brethren, when I came to you, came not with excellency of speech or of wisdom, declaring unto you the testimony of God" (1 Corinthians 2:1). The important thing to the one who bore this testimony was not how well he spoke or how wise he was, but the focus of his testimony. In the next verse he tells us what the testimony is: "For I determined not to know anything among you, save Jesus Christ and him crucified" (1 Corinthians 2:2).........

That's why the cross of Christ is not a morbid sight, but rather a wonderful sight. There Jesus rescued us from this horrible fate by suffering in our place. And He is the only one who has done that. We can't make ourselves worthy of God's favor. Neither can anybody else appease God's wrath for us. Only Jesus did that.

That means that only by trusting in Jesus' death for us can we escape outer darkness and be considered worthy to live eternally with Heavenly Father. Therefore trust in what Jesus has already done for you. 
That is a biblical testimony. That is apostolic testimony. That is a true Christian testimony.
