Answer:
No.
2 Timothy 1:9 Who hath saved us, and called us with an holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began, However – once we are saved we are to “do good works” and share the love of God with others.
To get into Heaven is the easiest thing because it is a free gift from God for all those who accept Jesus Christ into their heart. To become a disciple of Christ and follow Him means a lifetime of commitment and serving Him. I do believe there are different rewards we earn and even crowns we earn by our works here on Earth. Why would we need these things in Heaven? How about to offer unto God when we come before the throne!
