Dear Deepu C Varghese,
Your latest question is different from your original posting and the title.
Anyway, to answer you latest question, let me take you to Luke 17:5-10. There we see the disciple of the Lord asking for help from Him, for increasing their faith.
On the face of it, it does seem like a reasonable request and one would be led to assume that the Lord would work some divine way of increasing the faith of the disciples. However, if we read and study His reply, which is from v6 to v10, we see that Lord did not miracoulously do something to increase their faith. He told them that, even a small faith, as small as a mustard seed is enough to uproot a tree and be planted in the sea. In Matt 17, the Lord says that small faith is sufficient to move mountains. While the disciples assumed that they were lacking a sufficent amount of faith, the Lord pointed out that He is more interested in the quality of the faith, rather that its quantity. When it comes to faith, even mustard sized, can move mountains. In other words, the disciples already had the inner spiritual capacity for the faith that would sustain them, yes even move mountains - they just were failing to see their own responsibility to use it properly.
From there, He goes on to describe how masters relate to servants. In this parable, the Lord notes that the human masters do not thank their servants for doing their work. Nor do masters oblige their servants with kindness and rewards for performing what is expected of them. They remain unprofitable servants, even when they have done all that is expected of them. By this parable, the Lord is noting that servants have to obey whatever the master commands, with no incentive or help from the master. The master has hired them, because they can do what he wants done and he expected it done with no further help from the master.
The point in the parable is this - when we respond to God, we do so as servants respond to a master. God is our heavenly master and He expects our full hearted obedience in everything He commanded. As servants, we should not expect God to miracoulously divine that obedience in us - we have to find that faith and love and obedience to our heavenly Master, within us. We have to show willingness to obey, He will not divine that willingness in us.
Having said that, we can ask the Lord for help with our weaknesses - He is not someone who is untouched with our weaknessess. He is a compassinate Master (unlike the human master in the parable) and in Him are the oceans of grace that strengthen us and propel us. But we should display a willingness to obey and to do what He commands. When we obey, His grace will help us complete and fulfill His will in our lives.
I hope this helps you with your question.
