The Testimony of Salvation , Man’s or Christ’s?

The Testimony of Salvation , Man’s or Christ’s?  
A Brother gave verse and an up-lifting testimony of a man. Many will take hope from this, will up their faith and go on. But most will take the testimony to heart and, either not read the scriptures past what is given. Or focus on the testimony and not the scripture.  
What does this say about our Faith?  
We are taught that the Holy Spirit of Christ Jesus, the Living Word of God, in the Letter and Spirit, is the only way to salvation. The Word as written is Christ’s testimony from Genesis to Revelation.  
So, let us ask ourselves, why? Why do we seek and find more hope in the testimony of others and give our testimony before anything else first?   Instead of the testimony of Christ Jesus?   Why do we find more hope and comfort in the testimony that can save no one? Instead of the only testimony by which anyone can be saved?   Why our testimony and not Christ’s?  
The brother gave Colossians 2:13-15 with the testimony of a man. Now, let us look at the scriptures in context. Christ testimony.   Then ask ourselves which gives more hope? And which can bring salvation? Ours testimony, man’s testimony? Or Christ Jesus’s testimony?  
Colossians 2:6-23 AKJV As you have therefore received Christ Jesus the Lord, so walk you in him: rooted and built up in him, and stablished in the faith, as you have been taught, abounding therein with thanksgiving.   Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ. For in him dwells all the fulness of the Godhead bodily.   And you are complete in him, which is the head of all principality and power: in whom also you are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ: buried with him in baptism, wherein also you are risen with him through the faith of the operation of God, who has raised him from the dead.   And you, being dead in your sins and the uncircumcision of your flesh, has he quickened together with him, having forgiven you all trespasses; blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross; and having spoiled principalities and powers, he made a show of them openly, triumphing over them in it.   Let no man therefore judge you in meat, or in drink, or in respect of an holy day, or of the new moon, or of the sabbath days: which are a shadow of things to come; but the body is of Christ. Let no man beguile you of your reward in a voluntary humility and worshipping of angels, intruding into those things which he has not seen, vainly puffed up by his fleshly mind, and not holding the Head, from which all the body by joints and bands having nourishment ministered, and knit together, increased with the increase of God.   Wherefore if you be dead with Christ from the rudiments of the world, why, as though living in the world, are you subject to ordinances, (touch not; taste not; handle not; which all are to perish with the using;) after the commandments and doctrines of men? Which things have indeed a shew of wisdom in voluntary worship, and humility, and neglecting of the body; not in any honor to the satisfying of the flesh.   Now let us go forth as Christ commanded;  
Matthew 28:19-20 (KJV) 19 Go you therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: 20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.
