For me, I look at things in a realistic way.
As a parent, how would my children know that I am their father, if I am completely absent from their life? How would they know I care, if I never showed it?
So if God is, and created life, then he is either loving or unloving; caring, or uncaring.
If he is both loving and caring, then he would want his creation - his children - to know that. So instead of being absent from their lives, or not showing that he cares, he be there, and demonstrate that he cares.
From what I can see, he has done more than that.
Though invisible and absolutely awesome in power so that his very presence would annihilate his children, God left visible evidence of his being, and his supportive care.
Evidence #1
(
Romans 1:19, 20) . . .
what may be known about God is clearly evident among them, for God made it clear to them. For
his invisible qualities are clearly seen from the world’s creation onward, because they are perceived by the things made, even his eternal power and Godship,
so that they are inexcusable.
(Psalm 19:1)
The heavens are declaring the glory of God; The skies above proclaim the work of his hands.
(Acts 14:17) although
he did not leave himself without witness in that he did good, giving you rains from heaven and fruitful seasons, satisfying you with food and filling your hearts with gladness.
Evidence #2
God reveals details about himself (his name, personality, etc.), through his written word - a book like no other, and with a history like no other.
2 Timothy 3:16, 17
All Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight, for disciplining in righteousness, so that the man of God may be fully competent, completely equipped for every good work.
The witness God gives of the truthfulness of his word, is seen in the fact that...
1. Reliable prophecy is not of human origin - which the Bible is packed with.
(
2 Peter 1:20, 21) For you know this first, that no prophecy of Scripture springs from any private interpretation. For prophecy was at no time brought by man’s will, but men spoke from God as they were moved by holy spirit.
2. Scientific truths are revealed in the Bible long before being discovered by modern science.
3. The Bible evidently contains timeless practical value, and wisdom.
4. The Bible apparently contains a reliable history, of real people, events, and customs, etc.
5. The Bible contains one theme, and one story throughout, though a collection of writings from numerous, and various penmen - indicating one author.
Evidence #3
God shows his support and care...
1. through faithful human servant inspired or directed...
2. through his holy spirit.
3. through angelic support and direction.
4. through open communication via prayer, and real experience.
Because faith is not a possession of all people (2 Thessalonians 3:2), since it is a product of God's holy spirit (Galatians 5:22, 23), not everyone will benefit from the third line of evidence.
(Hebrews 11:6)
Moreover, without faith it is impossible to please God well, for whoever approaches God must believe that he is and that he becomes the rewarder of those earnestly seeking him.
Regardless of the amount of evidence available, there will be those who willfully ignore it, while claiming not to see it.
(Psalm 10:4)
In his haughtiness, the wicked man makes no investigation; All his thoughts are: “There is no God.”
(Romans 1:18, 21)
For God’s wrath is being revealed from heaven against all ungodliness and unrighteousness of
men who are suppressing the truth in an unrighteous way. . .
For
although they knew God [see evidence of his being], they did not glorify him as God nor did they thank him, but they became empty-headed in their reasonings and their senseless hearts became darkened.
(Ecclesiastes 3:11)
Everything he has made pretty in its time. Even time indefinite he has put in their heart, that mankind may never find out the work that the [true] God has made from the start to the finish.
