it's Pascal's wager for me;
Pascal's wager is a philosophical argument advanced by 
Blaise Pascal (1623–1662), seventeenth-century French mathematician, philosopher, physicist, and theologian.
[1] This argument posits that individuals essentially engage in a life-defining 
gamble regarding the belief in the 
existence of God.
Pascal contends that a rational person should adopt a lifestyle consistent with the existence of 
God and actively strive to believe in God. The reasoning behind this stance lies in the potential outcomes: if God does not exist, the individual incurs only finite losses, potentially sacrificing certain pleasures and luxuries. However, if God does indeed exist, they stand to gain immeasurably, as represented for example by an eternity in 
Heaven in 
Abrahamic tradition, while simultaneously avoiding boundless losses associated with an eternity in 
Hell.
