You wrote 'How can I accept Jesus Christ in my life?'
Then you said,
"To accept Jesus, you need to study the doctrines of christ Jesus."
To "accept Jesus" isn't even biblical.
But a natural man does not accept the things of the Spirit of God, for they are foolishness to him; and he cannot understand them, because they are spiritually appraised.
— 1 Corinthians 2:14
How one becomes saved is through faith. And Faith Alone.
How you worded it was "to become saved you must first study the Doctrines."
I'm not saying you shouldn't study doctrines, but if you're talking about salvation, you only need to believe in Jesus Christ.
can anyone believe in Jesus without learning about him first ? when the apostles preached in the book of acts to any unbeliever, they taught them first, then the unbeliever would accept to be baptized and confess the lord Jesus. Faith comes by hearing! It is the hearing of God's word that opens the heart of the unbeliever.
On the day of pentecost, the unbelievers didn't just believe in Jesus, peter told them the teachings of christ and the plan of God for salvation, that is the same thing as the doctrines of christ.
The first stage to salvation is for an unbeliever to give God their attention by studying God's word. Once that is done, it becomes easy for the holy spirit to convict them.
Again, no one gets saved by works, but for God to save anyone, that person must give his heart first. And that is, you must be willing let go off your own system for God to rule you.
thanks for your comment,
There is a lot more to be said.
