Ezekiel 14:4 says about people of Israel having Idols in heart. When we read the entire book of Ezekiel we know that God was angry with people of Israel because they made Idols for themself, defiled the temple of God, made vile images etc.
When God gave 10 Commandments mentioned in Exodus 20:2-17 and Deuteronomy 5:6-21 he made in very clear that :-
You shall not make for yourself an idol, whether in the form of anything that is in heaven above, or that is on the earth beneath, or that is in the water under the earth.You shall not bow down to them or worship them; for I the Lord your God am a jealous God, punishing children for the iniquity of parents, to the third and the fourth generation of those who reject me, but showing steadfast love to the thousandth generation of those who love me and keep my commandments.
But many times when we think of Idols, the only thing which comes to our mind is that of man made Idols we have seen or we see. But when we meditate on those things then we can know few things. Before that let me put 2 verses from New Testament. They are:-
1 Corinthians 3:16-17
Don’t you know that you yourselves are God’s temple and that God’s Spirit lives in you? If anyone destroys God’s temple, God will destroy him; for God’s temple is sacred, and you are that temple.
1 Corinthians 6:19
Do you not know that your body is a temple of the Holy Spirit, who is in you, whom you have received from God? You are not your own;
So we can know that now our hearts are the temple of God and Spirit of God dwells in out heart. But many times Jesus is removed from the throne of our heart and many things takes the place. When we meditate on this then we can know that many times many things become Idol in our life.
Anything which takes the glory and the position of God in our lives literally becomes an Idol. It can be our job, family, children, husband, wife, internet, music, movies etc. What all things snatches away the time which we are supposed to spend with God literally becomes and Idol in the way that it takes control of us and gradually takes us away from God and his presence.
Lets examine our life and see if we have any Idol in our life. If there are some then let us remove it and only have Jesus at the throne of our hearts.May God Bless You!
