How do I know what God's call is for my life?
Regularly, God called the prophets, and not the other way around. God does not say that all men want to be pastors unless they are called not to be pastors or elders. He establishes guidelines and few are the ones chosen to be the shepherds who are the ones that God really needs.
1 Corinthians 7:20 each must remain in the condition in which he was called. So that's the right question. Romans 12: 2 and do not adapt to this world, but transform yourself by renewing your mind, so that you realize what God's will is, what is good and acceptable and perfect in his presence. I believe that the will of God refers to the commandments of Holy Scripture, that you do not need a renewed mind to read and know something like you will not kill, it is known that this is against the will of God.
Romans 12: "In what way do the biblical teachings and all other relevant factors conspire to produce a direction for my life that God approves and blesses. The Christian mind is shaped by the word of God, while we pray and pray we ask God to transform us, put me in conformity with this word in the deepest part of my being.
We must know how to discern God's call for our lives, we are in this world to carry out the will of God and not to let ourselves be trapped by the system of this world. We are here to carry out the commission of our Lord and Savior, and we can have full confidence that He will provide us.
If you are not happy with what you are doing, this means that what you are doing is not a call from the Lord, your call is related to your passion for what you do. Example when the call of a believer is music, his passion, his desire and his desire will sing or play an instrument to praise and worship God, therefore that is your call.
