For we brought nothing into this world, and it is certain we can carry nothing out. And having food and clothing, with these we shall be content. 1 Timothy 6:7-8
There is certainly nothing wrong with having material things. Virtually everyone likes having nice stuff. The problem arises when we become engrossed in accumulating things. There is no reward in just getting more things simply for the purpose of having them around. I heard a preacher say once, “at the end of this life the richest person who ever lived and the poorest person who ever lived have the exact same amount of material wealth; nothing.”
The Bible clearly tells us that we can not take anything with us from this life into the next. All we need from God is essentially food and shelter. God always gives us what we need. Be content with what Christ has given you and where He has you. None of your possessions will go with you, but there can be many great eternal treasures waiting when you get to Heaven. Strive to get more of Christ, Walk in godliness and be content.
