filled with Joy and Peace...

v  God gives us joy!

And not only so, but we also joy in God through our Lord Jesus Christ,

by whom we have now received the atonement.

Romans 5:11 

v  God gives us peace!

Therefore being justified by faith,

we have peace with God through our Lord Jesus Christ:

Romans 5:1 

We cant have peace and joy unless we run to God. We can only have true joy and peace THROUGH Jesus Christ. If you look for it anywhere else, you wont find it!

Now the God of hope fill you with all joy and peace in believing,

that ye may abound in hope, through the power of the Holy Ghost.

Romans 15:13
