Matthew 6:19-21 Lay not up for yourselves treasures upon earth, where moth and rust does corrupt, and where thieves break in and steal. But lay up for yourselves treasures in heaven, where neither moth nor rust does corrupt and where thieves do not break through and steal...for where your treasure is there will your heart be also.
Dear friend, what is it you treasure most in life? Think upon this question for a while...think about how you spend your time; how you spend your money; what your thoughts are consumed by...and what matters most to you this hour. The answer to this question is undoubtedly what your heart desires most in life. Now take this exercise one step further and ask yourself based on your responses whether your heart's desires are earthly/worldly or whether they are heavenly/eternal. Do your answers show yourself to be a lover of the things of this world (i.e. material possessions) or a lover of the things of God?
If what you treasure most in life is of earthly/worldly importance you are selling your heart into bondage to things that do not benefit the soul and that will never bring you lasting joy and happiness! Instead, lay up for yourself treasures in heaven. As Albert Barnes remarks..."do not exhaust your strength and spend your days in providing for the life here, but let your chief anxiety be to be prepared for eternity. If you are a Christian then you are an heir of God and a joint-heir with Christ of an inheritance incorruptible, undefiled, and that does not fade away."
If God truly be the desire of our souls then our hearts will reflect this by treasuring up things of eternal value. Only you and the Lord know where your heart truly is this hour, but I earnestly plead with you that if you do not treasure God the most in your life...if there are things in this world that have replaced God as most important to you....you need to repent, pray for the renewal of your mind, and redirect your heart upwards.
