If you were to ask me to give you a reason to believe, I would tell you that a supreme God exists, The most compelling reason I have found is that there is a historical person named Jesus, whom it has been proven to have existed. This historical person claimed there is a God in heaven, and proved it by acts of miracles, some of which are documented.
If you were to ask me to give you a reason to believe, I would tell you that the Bible is an accurate account of the acts of this God and his Son Jesus: Gamaliel once said, “If it is from man, it will be overthrown, but if from God, you cannot stop it”. The Bible has been around for thousands of years and has more copies than any other historical document in history.
If you were to ask me to give you a reason to believe, I would tell you that the emptiness you feel in your life can only be filled by the God who created you. When God created man He put a place in their heart, an area that craves Him and can only be filled when you have that relationship with Him.
If you were to ask me to give you a reason to believe, I would tell you that having a relationship with this God cleanses your conscience, giving you an unexplainable peace with God, peace with yourself and peace with other people.
Do you have a relationship with this God and with His Son Jesus? If not all you have to do is realize you sin against a Holy God and accept His forgiveness by asking Jesus to come into your life. Immediately after the Holy Spirit of God will fill you with His presence leading you to the next step in your walk with Him.
If you want this relationship pray with me. Father God in heaven, You are holy and I am a sinner, please forgive me of my sins through the sacrifice of Jesus and fill me with Your Holy Spirits power. In the name of Jesus, amen
