Very easy, Uche.
Pray fervently. Serve others; widen the Heart; feel Love for all beings with a spirit of selflessness and Gratitude. Spiritual practices will help you.
Conscience is nothing other than the voice of God. This will become stronger with daily spiritual discipline. I have done this every single day for the last 35 years! Sometimes up to 7 hrs a day on retreats.
Vocal prayer, will take you to silent prayer. As the mind becomes calm, tranquil, a new force will take over; a new psychic thrill will fill the Heart, the spiritual Heart. This will manifest sweetness, Light; Love..
A deepening of the prayer will strengthen the intuition and you will be guided by a still small voice.
Actually, it is always here, but receptivity is essential. If you keep the windows closed, then the sun will struggle to come in. Open them. As to direct conversation, this is a much higher stage. Ones does not jump from Kindergarten to Uni. Patience and acceptance are essential Have Faith! Peace.
