There must be a holy living and uncompromising lifestyle. To sustain the fire, fasting and prayer should be observed regularly. Prayer is what sustains the fire and makes it burn always. Prayer is the oxygen that keeps the fire of God in our spirit burning with unprecedented flames.How do we become on fire for God? By allowing Him to burn inside of us.Some Christians are not fervent because their relationship with God is superficial. They jump in the fire for a short time and then jump out. Nothing much happens because they don’t spend enough time in the fire.Becoming fervent is not a complicated process. You just have to spend enough time with Jesus. When you put a pot of water on the stove, nothing happens immediately. Over time, the flame causes the water to boil.
