When you see the value in something, you'll seek to learn more about it. When people observed Jesus praying - they wanted to learn how to pray like him, and have a relationship with the Father like he has.
As long as it isn't just a mechanical reading (if your heart is in it), then there isn't anything wrong with repeating the words as taught by Jesus. He also didn't want to restrict us to just those words though.
1. The Lord's prayer has a structure. It isn't disorderly. There are 6 requests: the 1st three are God oriented and the last three are human needs. Before our needs are brought before God, pray for His glory and honor to submit ourselves to His will and remind ourselves who we're praying to.
2. The 1st line is "Our Father" - setting the tone for the prayer. It reminds us there is a relationship between God and us. Sometimes God will change the direction of our prayer.
3. Prayer isn't just about changing ourselves inwardly, but also about seeing results. Like, when we ask for our daily bread, we are asking for something to happen our lives. When God's people pray it will make a difference.
4. The Lord's prayer teaches us to think as a community; pray for others and become an intercessor.
5. One of the impacts of this prayer is that it gives us a deeper sense of out identity. If we come before God and call him father, then we will begin to see ourselves as his children. Remember to worship the Lord your God and that you are his servant; a sinful person who needs forgiveness and protection.
6. The Lord's prayer informs us of the proper spirit we are to have. Come to God with affection, trust, and humility.
