How do we know that God exists if we cannot see Him?

We know God exists through three main witnesses: creation, scripture, and conscience. Romans 1:20 emphasizes that the invisible qualities of God are made known through the things He has created. The heavens and the earth declare His glory, and each element of creation points to His divine power and nature. Furthermore, God has spoken through His Word, preserved in scripture, which contains the message of Christ and His righteousness. Finally, every person has a conscience that testifies to the existence of God, prompting an inner awareness of moral responsibility. Therefore, even without seeing God physically, His presence and nature are evident and undeniable for those who are willing to recognize it.
