The virtue of a Christian is to be prayerful. For someone to be called a true christian, the person must be prayerful. Prayer is a very important thing in christian life because it is a way through which we communicate with our creator and make our request known to him, so if we are not prayerful we can't communicate with our creator.
It's the obligation of a Christian to pray for everyone always including those who hate and prosecute us. The book of Matthew 5:44 teaches us to love our enemies, and always pray for them. A true christian is one who does not pray for himself alone, but also praying for others including those who do not love him.
So as christians, we should always be prayerful because if we are not not prayerful, the devil will conquer us. Let's always pray for everyone including our enemies in other to be a true christian.
God bless you all 🙏
