"Which turned the rock into a standing water, the flint into a fountain of waters". Psalm 114:8
There are some changes that only God can do. Salvation is one of them. Only God can save us. Only He can change us from being a lost sinner to a saved follower of Christ. We can't save ourselves. We can't change ourselves. No amount of effort and no number of changes that we make in our lives can bring about this transformation. All the changes in the world that we could make in our lives will not make us that new creation. (2 Corinthians 5:17) Turning over a new leaf, stop smoking, start going to church, start acting kinder, stop cussing, etc. No number of good deeds and good works can do it. It only happens when we come to Christ Jesus confessing our sins and putting our faith in Him as Savior. It is then when we are changed. It is then when we are forgiven and made righteous.
If you are trying to change yourself, if you are trying to be good enough to be a "Christian", if you are trying to do enough good deeds, you can't and won't ever be able to do it. It would be easier for you to take a rock and turn it into water than it would be for you to do enough good deeds to save yourself. It is impossible outside of Jesus Christ. He is the only way it can happen.
Have a great day. God can turn a rock into water. And only He can turn a sinner into a saved person.
