Asking Some Advice to become the follower of God

I am a lukewarm person; I know that is a sin because I am not obeying God to his commandment. I know that I am a sinner and that I am not God’s forgiveness. But I know God has never forsaken me for the sins that I did.
I am asking for God’s forgiveness for all my sins.
I am now trying my best to return to the church and our God.
Please be to know God more and learn His divine words so that I can help or teach other people.
Please give me some advice to help me become a follower of God.
