It is God’s will that all be saved and have eternal life with Him.
So many don’t seek this when they are young because they think they have time. They don’t think about dying young but you don’t really know how long you have.
People that have accepted Christ’s salvation know its importance and want it for their loved ones. They want those they care about to also have eternal life with Christ.
Many don’t realize this importance and may miss their opportunity. We that know need to keep on praying so that as many as possible will make that positive choice in Christ. Once a person enters eternity, they will no longer have that opportunity.
