Being zealous for God

“I am a stranger to my brothers, an alien to my own mother’s sons; for zeal for Your house consumes me, and the insults of those who insult You fall on me.” Psalm 69:8-9
This verse is one that is quoted in the New Testament as being prophetic of Jesus (John 2:17). In fact, the whole of this psalm contains prophetic insights into the life of Jesus, even though David was writing from his own personal experience. David was indeed shunned by his brothers (see 1 Sam. 17:28-29) and had great zeal for the house of God and upholding God’s name. Jesus too was shunned by his brothers (see John 7:3-5) and of course was zealous for the house of God, on two occasions turning over the tables in the temple of those selling animals and doves for sacrifice, and those changing money.
Are we zealous for God in this way? Do we feel offended when people blaspheme God’s name? Do we voice our objection, or do we say nothing and let it slide? The word ‘zealous’ is very similar to the word ‘jealous’. Both imply passion for something; jealousy on the negative side (not wanting to share it) but zealousness on the positive side. Being zealous for God means doing everything you can to promote Him. People are zealous for all sorts of causes today: civil rights, the environment, political parties, etc. As Christians, we should be zealous for the cause of Christ. I know I could definitely be more zealous for Him...
