Abraham Our Father In Faith

Abram believed the LORD, and it was credited to him as righteousness. (Genesis 15:6 BSB)

What did Abram believe? He believed that God would make a great nation out of him. He believed and he became the father of all who believe.

Then the LORD said to Abram, "Leave your country, your kindred, and your father's household, and go to the land I will show you. I will make you into a great nation, and I will bless you; I will make your name great, so that you will be a blessing. I will bless those who bless you and curse those who curse you; and all the families of the earth will be blessed through you." (Genesis 12:1-3 BSB)

Do we have something to believe like Abraham? Yes. God wants us to believe that we will reign with Him for a thousand years. Do we believe in this? Or do we believe in climate change and artificial intelligence and the end of the world? Things will get worse, but the world will not end. Ultimately, Jesus will come and rule.

Blessed and holy are those who share in the first resurrection! The second death has no power over them, but they will be priests of God and of Christ, and will reign with Him for a thousand years. (Revelation 20:6 BSB)

Be like Abraham. Believe in Him who is faithful.

He who calls you is faithful; he will surely do it. (1 Thessalonians 5:24 ESV) 

As it is written: "I have made you a father of many nations." He is our father in the presence of God, in whom he believed, the God who gives life to the dead and calls into being what does not yet exist. (Romans 4:17 BSB)

Christian Life - How to Keep It

There is a chapter in a book written by C. S. Lewis, Mere Christianity, where there is a chapter with the title, "Christians - Nice People or New Men". The link is a summary of the chapter and I think it is a good read for anyone who want to understand Christians.

I also quote from this sermon, "Sermon: C. S. Lewis on Christianity & atheism | Idler", which reflect on Christian life.

QUOTE
Do not think I am setting up baptism and belief and the Holy Communion as things that will do instead of your own attempts to copy Christ. Your natural life is derived from your parents; that does not mean it will stay there if you do nothing about it. You can lose it by neglect, or you can drive it away by committing suicide. You have to feed it and look after it: but always remember you are not making it, you are only keeping up a life you got from someone else. In the same way a Christian can lose the Christ-life which has been put into him, and he has to make efforts to keep it. But even the best Christian that ever lived is not acting on his own steam-he is only nourishing or protecting a life he could never have acquired by his own efforts. And that has practical consequences. As long as the natural life is in your body, it will do a lot towards repairing that body. Cut it, and up to a point it will heal, as a dead body would not. A live body is not one that never gets hurt, but one that can to some extent repair itself. In the same way a Christian is not a man who never goes wrong, but a man who is enabled to repent and pick himself up and begin over again after each stumble - because the Christ-life is inside him, repairing him all the time, enabling him to repeat (in some degree) the kind of voluntary death which Christ Himself carried out.

That is why the Christian is in a different position from other people who are trying to be good. They hope, by being good, to please God if there is one; or - if they think there is not - at least they hope to deserve approval from good men. But the Christian thinks any good he does comes from the Christ-life inside him. He does not think God will love us because we are good, but that God will make us good because He loves us; just as the roof of a greenhouse does not attract the sun because it is bright, but becomes bright because the sun shines on it.
