John 6:27
Labour not for the meat which perisheth, but for the meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed.

Our focus in this life will determine our faith walk here and eternity. The Son of man came to this earth, died for our sins so we can have everlasting life. However, we are not supposed to stop learning after being saved, we are supposed to keep pressing into the word. Jesus will help you learn and understand if you ask Him.
