There is proof through the scriptures that there is no rejection for any prayer that is made in the Holy Ghost, this makes it imperative for every child of God to have a strong desire to be filled with the Spirit of God, once we receive the baptism of the Holy Spirit our Christian experience goes through a quantum leap.
In certain times when we are overwhelmed and prayer lack its luster and we can not pray as we ought to, the Holy Spirit comes in to aid our prayer.
Praying in the Spirit gives your burden an expression in the divine realm.

Romans 8:26
