"When the Lamb broke the fifth seal, I saw underneath the altar the souls of those who had been slain because of the word of God, and because of the testimony which they had maintained;"
--- Revelation 6:9 NASB
Whatever the reason (love of the world, cold love toward others, or fear), we know the five foolish virgins let their lamps go out.
God gives us all a testimony to proclaim, not to hide.
Is it wise to hide it?
Therefore do not be ashamed of the testimony about our Lord, nor of me his prisoner, but share in suffering for the gospel by the power of God,
--- 2 Timothy 1:8-9
Our testimony in the end times is more powerful and important than many believe.
God uses our testimony, in part, to overcome Satan
(and by extension, the Antichrist).
"And they have conquered him by the blood of the Lamb and by the word of their testimony, for they loved not their lives even unto death."
--- Revelation 12:11
This verse changes everything.
I hope you can see how important our testimony is in the end times.
