The one thing that all humans have in common, past, present and future, whether they have any faith or not, is that we all age and die off of this earth. No one can stop it. Though I have struggled as a Christian, though I have failed, though I still have times when I'm angry with God, the Gospel of Jesus Christ, Salvation, is the only theology or doctrine that addresses human death in a way that makes sense to me. I don't mean that it makes sense to my fleshly, mental or psychological understanding. I mean that of all of the world's beliefs, it is the only faith-based, divine belief that makes sense to me.
Though we can study and learn about the things of God, the Kingdom of God that is given to anyone who wants to receive it is based on faith. This faith is in the revelation that God has given us about his Son. Those who love God through Jesus Christ are never able to make sense of many things in this worldly life. God has presented to us his answer and it is based in faith for as long as we are on this earth. Those who choose to believe in Christ's sacrifice continue daily to choose faith, no matter what is happening or not happening in their lives. Living in faith in The Son Of God can, however, make a difference in our lives.
Life on this earth can never be perfect but God has a plan that he has asked us to believe in. He wants us to hold to the knowledge until we leave here. Because we do leave here in undeniable death, it ties me to the truth of God's revelation of his Son and all that it implies. God asks us to believe in the salvation of his Son until the end. Whether each of us are on this earth or have died on, there will be an end to all of this horror, though for some it seems unlikely. The spirits of each of us lives forever, with God or without God. Physical death is inevitable. Spiritual death is not. We leave here but we are not gone because the spirit man cannot die. Salvation insures that those who choose to believe will live with God, forever.
In Biblical history, there was a great devastation that happened in the spirit world. It affected every human, past, present and future, and separated our spirits from God. Because it was not our fault and through his love for us, he provided a way for us to choose restoration of our spirits to himself. He made it simple so that anyone who wants it can simply choose to receive it. Anyone can accept and say that he/she believes that Jesus Christ is their only Savior, the Son whom God sent into the world. That's all.
We don't have to live a certain way. We don't have to do certain things. We don't have to stop doing things or start doing other things. We only need to choose to accept the truth of Salvation through Christ Jesus and mean it in our hearts. The good thing is that not only has God provided a way out of separation from him, he will also help us to accept the truth. He knows the hearts of every man and knows those who would like to believe and accept. He's a good God, the only wise God and the one true God. No one has ever lost out on a chance to accept Jesus as their Savior and never will. He's so very merciful and it is his desire that everyone should be saved.
