Hi Abena @_ab.na. I am glad you are here, as you said you took a break to try and fix your own faith first. I commend you for doing that because now you are making Christ, your own. Not your family’s or not your community’s. You are going to be a blessing for many.
On a side note, having doubts is only natural. God is not scared of our questions. That’s why he says come to me and pray. So we understand who he is. Prayer is not about getting our way but actually aligning our will with God’s will. For that to happen we have to ask and understand who God is and why he does what he does and why his ways are superior than ours. God knows all about you and I. he wants honesty, you cant fake it and stay the same when you are doubting. You have to come to God and say why or show me the way. A closed heart and arrogance is not the way but a sincere question is always welcome.
John 20: 25 The other disciples therefore said to him, “We have seen the Lord.” So he said to them, “Unless I see in His hands the print of the nails, and put my finger into the print of the nails, and put my hand into His side, I will not believe.” 26 And after eight days His disciples were again inside, and Thomas with them. Jesus came, the doors being shut, and stood in the midst, and said, “Peace to you!” 27 Then He said to Thomas, “Reach your finger here, and look at My hands; and reach your hand here, and put it into My side. Do not be unbelieving, but believing.” 28 And Thomas answered and said to Him, “My Lord and my God!”
Now to answer your question, there is a great outline one of the speakers on ask RZIM recently did but I will organize it with added resources below.
To start with, a lot of people who ask for proof of God, usually tend to use the scientific method. But we have to remind them there are many ways to “prove” or show it is likely that God exist even if we cant make God show up like a genie (This is not Alladin ). For instance in the court system, they cant reproduce the murder, they just use hints, clues, and arguments to show it was probably the case for the murder. So the things I will present below will have a mix of them.
1.The Kalam Cosmological Argument (philosophical argument): The universe had a beginning. Anything that has a beginning must have a cause. You cant bring matter-space-time out of nothing. And the cause for the matter-space-time has to be outside of itself because it cant cause itself. Such a cause has to have a causer. The “causer” has to be beyond time, all powerful, eternal, uncreated, and spaceless. Here is a great video from William Craig that summarizes that really well.
2. Design and fine-tuning of the universe argument (scientific evidence): Looking at the world and the laws of physics and nature, it is perfectly tuned for life to exist. Science says so. Not just for man to exist but for any life to exist. Chance/evolution cant just do it despite scientists persistence to that theory. But if it is designed by a designer then that is possible. No one says this computer I am typing with came out of a thin air by chance. No, a designer like microsoft or apple took their time to make it. Well our God is so powerful, he just called into an existence . Here is another great video from the same place.
3.The Moral argument: As ravi says a truth claim (say one thing is good or bad) cant be made using science. Science can only tells us how things happen, But it can never tell you why or if you should or can do anything. Making a moral judgement is beyond science. To make a moral judgement, we need objective moral laws. To have objective moral laws, we need a moral giver. A perfect standard. Only God is perfect. That indirectly proves that God must exist if we think there are moral laws that we all should abide in. For instance, it is never okay to kill children for fun. It is not subjective or an opinion. It is always true. Here are two videos that do a great job to explain it. .
4. The historical Evidence for the life, death, and resurrection of Jesus
So the top three arguments/proofs help us see there is definitely a great probability for a God who is powerful, personal, eternal, outside of matter-space-time to exist, but then we encounter the God of the bible. The son of man/God, Jesus who was there from the beginning of time (the Word), takes a human form and takes part in human history. Anyone can claim to be God, but the one thing about a God, if you ask me, is the one that can raise the dead, give sight to the blind, cure illness, walk on water, forgive sins, and above all is personal, cares and have the moral principle of a God. He died for us. He is the ultimate of everything. Here are a few great videos as well. Dr William Craig is awesome.
5. Personal Evidence/Experience
Last but not least is our personal encounter with the Living God. Someone cant say they know the ocean because they put their feet near the shores. Experiencing Christ and living side by side with God daily is something that cant be taken lightly. Here is a quote and a great video by Ravi.
I believe in Christianity as I believe that the sun has risen: not only because I see it, but because by it I see everything else. - C.S Lewis
I hope this helps. Keep asking, keep seeking. You’ll find it. You’ll be strengthened, you will be unshakable. With that many can be saved.
Matthew 7: 7 “Ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. 8 For everyone who asks receives, and he who seeks finds, and to him who knocks it will be opened. 9 Or what man is there among you who, if his son asks for bread, will give him a stone? 10 Or if he asks for a fish, will he give him a serpent? 11 If you then, being evil, know how to give good gifts to your children, how much more will your Father who is in heaven give good things to those who ask Him!
I will also leave you with a great quote by Alex Vileken (well known physicist) said by John Lennox.
"An argument is what convinces reasonable men, and a proof is what it takes to convince even an unreasonable man. "
God Bless You
