For God’s gifts and his call are irrevocable

 Romans 11:19-36

Granted. But they were broken off because of unbelief, and you stand by faith. Do not be arrogant, but tremble. For if God did not spare the natural branches, he will not spare you either.  Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you, provided that you continue in his kindness. Otherwise, you also will be cut off.

And if they do not persist in unbelief, they will be grafted in, for God is able to graft them in again. After all, if you were cut out of an olive tree that is wild by nature, and contrary to nature were grafted into a cultivated olive tree, how much more readily will these, the natural branches, be grafted into their own olive tree!

Israel has experienced a hardening in part until the full number of the Gentiles has come in, and in this way all Israel will be saved.

For God’s gifts and his call are irrevocable. Just as you who were at one time disobedient to God have now received mercy as a result of their disobedience, so they too have now become disobedient in order that they too may now receive mercy as a result of God’s mercy to you. For God has bound everyone over to disobedience so that he may have mercy on them all.

Oh, the depth of the riches of the wisdom and knowledge of God!

How unsearchable his judgments, and his paths beyond tracing out!

“Who has ever given to God, that God should repay them?” For from him and through him and for him are all things. To him be the glory forever! Amen.

Why?

Do not be arrogant, but tremble for all of us and need to stand by faith.

When the full number of the Gentiles has come in, and in this way all Israel will be saved, so God's people will be saved in God's time schedule.

The Lord can graft Gentiles to an olive tree, so more natural let the natural branches to be grafted into their own olive tree!

How?

Pray to the Lord, may I be able to walk on the way of God's schedule and God's plan, be humble and tremble every day.
