I am deeply convinced that the existence of God does not necessarily begin in a classroom or laboratory, it is something in the ordinary life. When looking around us we observe order, beauty and purpose. The sun sets and rises at the opportune time, it is in the season of the rain that the land yields a harvest. According to the Bible, Psalm 19: 1 explains that the heavens are a declaration of the glory of God. There is a great creator behind all of nature itself.
The other powerful evidence of the existence of God is the human heart. Worship, love and good are something we deeply desire in our hearts. People still believe in a higher power, this is the voice that speaks to us about what is right or what is wrong, leading us to God who had set His law in our hearts.
God manifested Himself in the lives of many people in the Bible. People that were violent, hopeless or lost become peaceful and have purpose when they met God. Love, conscience and faith are several things that can not be explained by science fully. Ultimately, the existence of God is justified by not only what we observe in the surroundings but also what we feel in us.
