The things you accumulate.
The apostle Peter writes,
"Praise be to the God and Father of our Lord Jesus Christ! In his great mercy he has given us new birth into a living hope through the resurrection of Jesus Christ from the dead, and into an inheritance that can never perish, spoil or fade kept in heaven for you" 1Peter 1:3-4.
If you accept the saving grace offered to you by God through Christ Jesus. Then you can praise God because the inheritance we have is not in this world but in heaven where it can never spoil or fade.
The riches you may accumulate in this world are fleeting. At the end of your life they will be dispersed among other people. They will no longer be yours. But the things you do for Christ. The things you do for God will be yours forever.
Please think about it.
