This is very important for a Christian to live a prayerful life. A Christian must pray, must fast and study the word of God. So when we pray, we are sure that we will receive answer from God.
We have to pray for those, our loved ones, our enemies, even those that go against our will. Matthew 5 verse 14 also says that. But I say unto you, love your enemies, bless them that cause you do good to them that hate you and pray to them with despitefully use you and persecute you.
We must also pray for those who do us wrong, pray for enemies, pray for those who need prayers. This is a virtue to become a Christian. We must pray for people, we must pray for others, pray for our human, pray for our fellow humans, and we must show love.
A life of prayer is very good as believers. We need to communicate to God daily and prayer is one of the important things that we can communicate to God always and every time.
