I Coirnthians 1 :22-24 For Jews demand signs and Greeks seek wisdom, but we preach Christ crucified, a stumbling block to Jews and folly to Gentiles, but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God.
What is Paul referring to? Their job? Being a firefigher? Homemaker? Waiter? General Manager ? NASCAR Racer? No. He is referring to the work of God in calling them to Himself out of darkness into light, out of death into life. You can see the meaning pretty clearly in verses 22-24: For Jews demand signs and Greeks seek wisdom, but we preach Christ crucified, a stumbling block to Jews and folly to Gentiles, but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God.
So there are three groups in these verses: the Jews, the Gentiles, and "the called." Or to be more precise: the non-called Jews, the non-called Gentiles, and the called Jews and Gentiles. And what's the difference? The non-called Jews see Christ-crucified as a stumbling block (verse 23). The non-called Gentiles see Christ-crucified as folly (verse 23). But "the called" Jews and Gentiles see Christ-crucified as "the power of God and the wisdom of God" (verse 24).
When we say God calls, we mean the work of God that unlock our eyes to see Christ as the right and true and wise and all knowing and the call is so compelling that we receive Him for salvation. God's call is His life-giving order or instruction with authority. Come. If you are a believer today, that is how you came to be a believer, a Christian or became born again, this is how you got saved.
Now what this call of God will produce in you exactly what it called for. In other words God called you out of darkness into His marvelous light. The call my friend was effective, that is causing result, the desired result happen. I can tell you when God gives a call to you; it will produce what it calls for.
It is like someone comes over to you when you are in a dead sleep, and gives you a command to wake up. And you know how it is, you leap upright. In other words, when you hear the command or the call of God in your ear, you did not ponder and then decide to wake up. When God calls you woke up. The command was "wake up" and that is what happens. That is how God raises us up from spiritual death. And only God can do it. And you know if you are a believer that is how you became a believer. That is what Ephesians 2:4 says, that God made us alive when we were dead. The true was you were about to sleep yourself into hell, and our gracious God work you up to the cruelty of sin and the loveliness of a great Savior.
