What would happen if a non-believer repented and was baptized, in Jesus name? (Christians only)?

If an atheist or non-believer were to kneel on there knee's and say "Father in the name of Jesus forgive me of all of my sins..Please Lead and guide me to your will for my life" in Jesus name I pray, amen..Would he or she be accepted by God Almighty, if they asked it with a sincere, repented heart..This question is for christians only..If you say something that is extremely negative I will openly pray for you (smile)
