There is no question that God can save us. Of course He can make us inheritors of "the land" and give us eternal life. All these are beyond question! He has the power to do this, and He has the will to do it. He certainly wants to do it—it is part of His purpose.
Even so, we can stop the process. We can choose not to be sanctified. This is why Paul says, "Work out your own salvation." We learn from the analogy of Israel in the wilderness how the first generation of those who came out chose—they made the choice—to die in the wilderness. It was not God's purpose that they die there. He had the power to get Israel into the land. Indeed, He did it. Yet, their lack of faith, their disbelief, their stiff necks, the fact that they never got rid of the patterns of thinking they had in Egypt, they would not yield, they refused to make the right choices (as Joshua and Caleb did) were the deciding factors in their bodies being scattered all through the wilderness. God had it written down as a lesson for us (see I Corinthians 10:1-11). He is saying, in effect, "Choose life. Don't choose to do what these people did—in lusting, tempting Me, and so forth."
So, who can we possibly blame if we do not make it? Has not God called us? Has He not given us His grace? Has He not given us His Spirit, a new heart, the divine nature, access to Him, the promise that He will never give us any trial that is too great for us? And let us not forget he additional promise in Hebrews 13:5, "I will never leave you nor forsake you." He has given us all the tools, so now the onus is on us.
God is not demanding that we do everything perfectly from day one, but He does want to see evidence that we want to be there! He wants to see that we are making efforts to walk the talk. He wants to see that we are not going backwards. He wants to see us move off dead center and that we begin to grow on a steady, consistent basis—regardless of how fast it is. He wants to see that we are using and applying what He has given to us, and He is willing to add whatever we lack! He will give us the gifts that we need in order to serve Him. If we do what He wants us to do, the changes will take place.
The mainstream Christian approach leaves one with the impression that salvation is complete at the point of justification. But that is completely out of step with Colossians 1:22, where Paul writes, "if you continue in the faith. . . ." Israel had to walk to the Promised Land, and as they walked, God prepared them to inherit the land. In this way, they became sanctified. Sanctification is what gives evidence of growth.
