How do we know that the death of a believer is better than their birth?

The teaching that the day of death is better than the day of birth is rooted in the reality that upon death, believers enter into a state of perfect rest and worship. As stated in 2 Corinthians 5:1-8, when we leave this earthly body, we are present with the Lord, which is a far better state than our current existence filled with sin and struggle. The joy of being in the full presence of God, as well as the relief from earthly troubles, supports this claim, making death a gain for the believer.
