Hi bornagain,
So glad you want to go on in the Lord.
Now it sounds like you were both looking for the `beautiful experience,` & it was accompanied by the hype that people often give, (well done, great, blah, blah...) to those who respond to a call to receive Jesus. However the repentance has not been emphasised, (by the speaker) and thus you have just mentally done something. To actually be `born again,` you need to repent of all your sins and receive Jesus as your Saviour who paid the awful price for our cleansing.
Then you need to realise that there are so many things we have in our lives, in our hearts that we need to consciously repent of as they come to the surface for we have let them control us. eg, wrong, selfish sexual gratification, just letting the self rule. Those desires will choke out the new life that is growing inside of you.
This is the time for you to start to exercise some spiritual muscle and learn to grow. As enoob has told you, what you feed on will become the dominate one. The enemy wants to control you, (let you have your selfish ways) but the Lord desires to guide you and make you strong in Him.
You need to choose - slothfulness or exercise spiritually & daily, (like developing physical muscle, develop spiritual `muscle`.)
praying, Marilyn
BTW as to your boyfriend, I think you need to work on yourself and hopefully in time he will see the difference and choose to grow himself. I think that many young converts think that God is going to do all the work for them and they can just sit back and have `beautiful experiences.` That is a lie and not `growth,` just selfishness.
