He said yes

When he heard this, Jesus said, “This sickness will not end in death. No, it is for God’s glory so that God’s Son may be glorified through it.” 
(John 11v4 NIV)

This was Jesus’ declaration of faith. 
He was making a statement which appeared not to be true.
Lazarus did die (but not for long). 

However, He made it clear that there was a bigger issue here. 
He recognised what this event would signify. 
Are you willing to allow God to be glorified in and through you? 

It may not be comfortable but it will be glorious. 
Do you still trust Him even though it looks hopeless?
Ask Him to help you believe and overcome your doubt or uncertainties.

Make a list what you have given up on.
Ask God to forgive you for doubting. 
Ask Him how to persevere. 

He never gives up on you.
