Many things couple together naturally e.g. salt coupling with pepper.
For a Christian, prayer couples with the Word of God. Prayer and bible reading and study must not be missing from one's life.
Christians must not walk their journey without extensive bible reading and studying. Christians must not walk their journey without much labour in prayer.
A Christian who reads, understands and applies the bible in context, is able to pray more according to God's will (Hebrews 5:14). A Christian who prays or petitions according to God's will, receives from the Lord (James 4:3).
There are many prayers in the bible. Just to name a few: prayer from Hannah, song of Moses, prayers from Solomon, prayers from David (and all of the other psalms), prayers from Jesus etc. As a personal study, today I encourage you to go through the prayers by other saints in the bible and see and learn how they prayed.
Let us daily pray and read the Word of God.
