There is nothiing more compelling in Christ than what exists in other religions .
Here are two compelling reasons:
Freed From Works
All the religions you cite stress works. The JW's stress works. Jesus liberates a person from the tyranny of works. Having been liberated, I would never return to that bondage. Jesus stresses belief as the "work of God". Good things (fruits of Spirit) naturally flow from that rest, and are evidence of that belief.
"For he who has entered His rest has himself also ceased from his works as God did from His." - Hebrews 4: 10
Freed From Condemnation:
"He who believes in Him is not condemned; but he who does not believe is condemned already" - Jn 3:18
We are born into a condemned condition; having been severed from the family and righteousness of God, we inherited the sin, family, & condemnation of ADAM.
All will be judged; that is man's destiny after death. Hebrews 9:27 makes this clear; "it is appointed unto man once to die, and then judgment". This is the ultimate duty of God as lawgiver. The Good News is that not all will be condemned.
Further, the very one who offers to die in your place will be YOUR judge:
"Him God raised up on the third day, and showed Him openly, not to all the people, but to witnesses chosen before by God, even to us who ate and drank with Him after He arose from the dead. And He commanded us to preach to the people, and to testify that it is He who was ordained by God to be Judge of the living and the dead. To Him all the prophets witness that, through His name, whoever believes in Him will receive remission of sins.” - Acts 10
And who can forget this plea: Come to Me, all you who labor and are heavy laden, and I will give you rest. Take My yoke upon you and learn from Me, for I am gentle and lowly in heart, and you will find rest for your souls.
In the end, God simply gives people what they request. If you want works, God will judge you by your works. If you believe God, you "WILL NOT be condemned."
