Child of God, I believe that God has given you a desire to serve him in the medical profession. Yes the desire was planted by him. Now the enemy seeks to kill, steal and destroy. Do not let the enemy rob you of your joy or calling. The bible says that God is not the author of confussion. God speaks to us through his word and faith comes from the hearing. You are not lost, God knows exactely where you are and who you belong to. Your identy is secure. Just bloom where you are planted, study hard and be encouraged. Keep talking to God, tell him how you feel and he will hear. God will speak to you in due time, just wait on him, trust him and keep walking behind him. Bless you. It will be o.k. I know it. Don't give up. Never settle for less than God's best for you.
