There is this sensation of joy of fulfilment when one has positive results from whatever thing he puts his or her hands into. There is no joy in a fruitless effort. There are many things that people do that do not bear fruit. We have joy when our labour bears fruits.
Prayers can be fruitful and it can be fruitless. A fruitful prayer is the one which brings answers. The prayers that do not bring fruits are fruitless. We should consider how we pray so that we do not pray the kind of prayers that are fruitless.
For our prayers to bring answers, we should know that we are praying to God. Our God does not listen to those who do not obey Him. He does not listen to sinners. So, we should run away from every appearance of evil. We should not keep offenses in our hearts. We must be holy before the Lord.
We should always pray in faith. We should pray while wavering. Anyone who wavers cannot receive anything from God. It is the prayers of faith that God answers. We cannot please God without faith. Let us always trust that God is able to do whatsoever we are asking from Him.
