There are some arguments that are not really worth spending time on. For anyone to be able to believe God it takes
a sincere and willing heart. God does not force Himself on anyone, but He reveals Himself to those who seek Him honestly.
God doesn't necessarily needs anyone's approval before He is called and recognized as God.
Even when we have doubts and questions the evidence of God can be found in creation and also in areas of our lives. The way the world is structured it points to the fact that there is a Creator who is intentional and present.
Psalm 19:1
"The heavens declare the glory of God"
We cannot truly encounter God while ignoring His presence or shutting our ears to His voice. Many struggle to see God because they search only with the mind and not with the heart. It is in trust and faith that God becomes real to us.
Hebrews 11:6
"Anyone who comes to Him must believe that He exists"
When we draw closer to God, He makes Himself known. It does not work in the reverse order. When our hearts are open the reality of God is made visible to us.
