I trust what Jesus says. I find it interesting what some people say expounding on the Scriptures but when it comes down to them and Jesus' words I will always choose Jesus' words. I know a few people who have married themselves to certain doctrines that are not found in the Word, that fly in the face of what Jesus said. One of these things is that our loving Father has decided who will be saved and who won't be. This means that no matter what some people decide, salvation will never be available to them.
Can we just review here what Jesus said?
Look at it again. Jesus said "everyone" who has faith in him. Other translations says "whoever believes" in him. I don't need to go any further than these words. It is the promise I rely on, where I have placed my faith and trust, because of the one who said it.
My salvation is not a thing given to me because Yahweh has considered my favoured but because I believed in the one single act where Father sent the Son to die for the salvation of the entire world. Salvation is a free gift for everyone who decides to believe. We will be judged not according to our sins but according to whether we believed or not, whether we placed our faith in the Son of God, trusted his promises and accepted the gift.
Father has chosen to love the entire world of people, even in the midst of our rebellion, in all our ugliness, in all our guilt and shame. It is when we accept the promise that the promise is applied and everything is removed. None of this was done by me; my only part is to accept it, but it is my choice. Father has not chosen some to be saved and some to be condemned. He has chosen us all to be saved but it is up to us. He has given us a choice. That is what Jesus said and that is good enough for me.
