Psalms 19:1<> The heavens declare the glory of God; and the firmament sheweth his handywork.
50:6 And the heavens shall declare his righteousness: for God is judge himself. Selah.
97:6 The heavens declare his righteousness, and all the people see his glory.
Few people acknowledge the extent of the universe, and how it can reach into the world of witnessing and impact people forever! I have heard lectures about the amazing stars and galaxies that we have explored and all of them have sprung into a great gospel message!
For example, you might meet someone who has a big problem with God being so “omni” everything. You say He is everywhere at every time at every thought and at every circumstance. In short, you can’t escape Him.
But, the man or woman doesn’t understand. So, you tell them about the amazing stars, galaxies and nebulae that exist in outer space. Then, you tell that person that God created those magnificent beauties.
All of a sudden, that person can understand, at least, slightly, the “omni’s” of God. He or she can understand the unlimited-ness of God, they understand His creation and purpose for creation
Note: when using astronomy to witness make sure you keep it biblical and that you don’t state man’s opinion as fact and God’s Truth as opinion. Also, make sure the focus is on the Salvation!
