Here, Paul is specifically praying for a 'spirit of revelation'. Yes, God still speaks today~! He speaks through His Word, through His anointed messengers and through personal revelation by the Holy Spirit.
We daily need God's revelation and personal 'rhemas' for guidance, direction and divine wisdom.
I did not receive it from any man, nor was I taught it; rather, I received it by revelation from Jesus Christ. [ Galatians 1:12]Let us make sure we receive God's revealed Word personally before passing it on to others and let us be open to God's personal revelations today.
~ True wisdom and revelation starts with a heart full of faith, not a head full of facts ~
