God shows common grace to all. For example, common grace gives us rain with fruitful seasons, providing for the natural needs of all mankind. God's goodness to all is common grace. Yet, common grace is not saving grace.
God's saving grace is in Christ. The only way that you can have a personal relationship with God is through grace alone in Christ alone. He must reveal himself to you and in you. That has been appropriately called amazing grace. It's not what you do for God. It's what God has done for you in Christ. All that you are or ever hope to be is by the grace of God.
God's saving grace is to believers through the gospel (1 Corinthians 15:1-4). Every believer's testimony echoes the words of the apostle Paul, "But by the grace of God I am what I am, and His grace toward me was not in vain" (First Corinthians 15:10). Grace gives all the glory to God. That's because grace is always God's gift to you, that you never merit nor earn.
God's saving grace is freely given. There is no way you can merit nor earn the favor of God. It comes to you only as a gift to be freely received (Ephesians 2:8-9). Faith in Jesus Christ receives the grace of God. Don't fall for the idea that you can somehow be good enough to merit God's gift. Grace is not for good people. Grace in Christ is offered to sinners, and that includes all of us (Romans 3:23).
