The Bible has much to say about being sincere in our worship of God. Deuteronomy 4:29, for example, instructs us to seek God with all our heart. In ancient times people would tear their clothing to show humility, sorrow or respect to God. In Joel 2:13, God told them to rend their hearts instead of their garments. This teaches us that God is most concerned about how we think. Our attitude is the critical factor. The point is that people can dress a certain way to give an appearance of righteousness, but still not really be devoted to God. Though some clothing does have catchy, biblical messages, which are far better than the messages on many shirts, wearing them doesn't prove your inner attitude.

So how can we make sure of our sincerity toward God? One way is through prayer. In Psalm 51:10, David asked God to create in him a "clean heart." David realized that he had sinned and came to God for forgiveness. We can do the same. We can also tell God of our sincerity and ask Him to help us concentrate on the important spiritual matters each day. Bible study is another way we can make sure we keep God's perspective in mind. Those who study and pray on a regular basis are ones who preserve and build a sustained relationship with God.
