Jesus was addressing his disciples, telling them that if they would keep his commandments, they would enter into a good and abundant life, as they sojourn here on earth. If the "life" were to mean eternal life, then it would suggest that eternal life would be awarded for their good works, and that is a false doctrine.
I notice you cut out the beginning part, the first question. Let's go back into Matthew 19: 16 And, behold, one came and said unto him, Good Master, what good thing shall I do, that I may have eternal life? 17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments. People we must realize, that it is the keeping of God’s holy laws that separates the righteous from the unrighteous and the Saints from the Sinners. (Titus: 3:8) This is a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God might be careful to maintain good works. These things are good and profitable unto men. You must learn (by the word of God) what God expects of you and maintain his expectations to the end, if you expect to be saved. Jesus says in (Matt. 5:16) Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven. You are supposed to glorify your Father in heaven, and let your light shine before men.
