That’s allegedly promised after death, if conditions are met. This question pertains to the here, and now.
So I would assume Islam. I don't know specifically what Islam teaches about what they 'offer' in the here and now... but I do know that what Christianity teaches.
The here and now, is not what Christianity is about. Christianity is entirely about what comes after. There are numerous proverbs, and statements, that indicate this in the Bible.
Matthew 6: Jesus says-
Do not store up for yourselves treasures on earth, where moths and vermin destroy, and where thieves break in and steal. But store up for yourselves treasures in heaven, where moths and vermin do not destroy, and where thieves do not break in and steal. For where your treasure is, there your heart will be also.
Or you can look at James 4:14
You do not even know what will happen tomorrow. What is your life? You are a mist that appears for a little while and then vanishes.
Or you can look at Hebrews 9:27
Just as people are destined to die once, and after that to face judgment
Psalm 90:9
All our days pass away under your wrath; we finish our years with a moan.
And there are honestly hundreds of verses that all point to the fact that this life, is not the big thing. This life is the chance to get ready for the big thing.
The big thing is what comes after this life.
Ecclesiastes is my favorite book of the Bible, because it points out the reality of life. 9:9
Enjoy life with your wife, whom you love, all the days of this meaningless life that God has given you under the sun--all your meaningless days. For this is your lot in life and in your toilsome labor under the sun.
Bible believing Christians are not trying to make this life our utopia, and we're not Christians because we are hoping G-d will give us stuff here.
We are waiting for the return of Christ, and a future in Heaven where there is no pain, no suffering, no illness, no old age, no terrible diseases, no betrayal, and back stabbing, no evil at all.
This is why 21 Coptic Christians from Egypt were captured and beheaded by ISIS in 2015, made no sound on the sandy beach in Libya before they had their heads cut off. I know, I watched the video ISIS put out of the slaughter.
If they became a Christian, because of what Christianity offered them in this life, they should have contacted the authorities to press fraud charges.
No, they became a Christian because in eternity, they will be rewarded for their faithfulness right up to the end.
Now that doesn't mean all Christians will be martyred. Obviously Christians in many parts of the world, live very good lives relative to others. But that is still not the focus of Christianity.
So if all your asking about, it what does Christianity offer you here in now... not much. G-d promises very little, except that he will be with you in the dark times, help you through the suffering, and walk with in this life up to the end.
