We should develop our intimate relationship with God. We have to give our time to read the Bible, meditate on it and apply to our personal and corporate life. Besides, we have to listen to the still voice of the Holy Spirit in anything we do. In other words, we have to be sensitive in the voice of the Holy Spirit.
Prayer should be one of an inevitable key that we can not ignore for strengthening our faith because that is the time when we are told the wisdom of God. Besides, time to listen from other's experience. God often use other people to correct an strength our faith.
