There is plenty of prayers in the bible. Some examples include:
- The Lord's prayer
- The high priestly prayer
- Hannah's prayer
- Isaac's and Israel's blessings over his sons
- Solomon's prayer
...and the list goes on.
I would encourage you to go through the prayers in the bible and study it. Many prayers can be about extolling our Lord's greatness, majesty and power. Other prayers can be about asking the Lord for His strength or even about repentance e.g. Psalm 51.
If we can do a personal in-depth study on each prayer in the bible, how much will our knowledge, appreciation, motivation, perseverance, desperation of our prayers and prayer life be enriched?
