How I live my life affects how people see me. How my family behaves affects other people’s attitudes. How Christians behave in this world affects how people in this world view God because Christians are supposed to reflect the character of Christ.
We need to guard our hearts when we worship God. Give careful thought to how you worship. Why was that? Because our approach to worship is important. If it’s not that it will be not accepted by God and thus will be useless.
