The way you store up treasure in heaven is by investing in getting people there.
Invest your time and talent in sharing the word of God. Don't be afraid, God will be there with you giving you the strength and courage to brag about His Son – your savior.
I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me.
