The first thing is that the only way to obtain salvation is through the death of Christ on the cross, there is no other way, it is not something that we can obtain by ourselves or by our good works. The only work that has been able to satisfy the divine will of God is the death or the finished work of Christ on the cross, that blood that gave us salvation and eternal life. The only one who can save us is God, so trying to save ourselves by our own strength is an attempt that will always fail.
We already know that salvation can not be obtained in a human way, but it is a divine intervention, but we must also understand that we are not Christians to sit or do what we want, we must act, even if the works do not save us, we must understand that a saved Christian will do good deeds, behave as such, live as such.
2 Like newborn babies, crave pure spiritual milk, so that by it you may grow up in your salvation,
3 now that you have tasted that the Lord is good.
1 Pedro 2:2-3
We must wish as children the Word of God. If you are really a Christian, what you should most desire in your life is the Word of God, to desire it as a child wishes to drink milk, because this Word is what makes us grow in this way, which makes us grow to be true Christians , then, is the only way to know the only true God.
Let us continue to grow for salvation on this path and remember that there is nothing more important than our God, that He shed His precious blood for us on the cross and there is nothing with which we can pay, we only have to live a life submitted to Him and His Word.
