The Bible tells us to love God with “all thy heart, and with all thy soul, and with all thy strength, and with all thy mind.” (Luke 10:27) Having a faith isn’t something that we can do half-heartedly. Look at Esther: with her famous “If I perish, I perish,” she risked her life to carry out God’s will to save the Israelites. Perhaps a more prominent example would be Paul the Apostle, a convert who became the greatest proselytizer of early Christianity; the saying “there is no greater proselytizer like a convert” didn’t just come from nowhere. Likewise, God demands us to pour our hearts and dare ourselves to achieve His will.
But we must approach this idea with caution, for God only demands a specific kind of passion: a passion to carry out what God has deemed to be right, not what we think is the best for Him or ourselves. Sometimes, we might be overzealous and act according to our best intentions and as a result displease God. This is because our best intentions don’t guarantee agreement with that of God’s. Just look at David for instance. David believed that the best way to move the Ark of the Covenant was to bring a fancy cart to carry the ark and it with guards and trumpets and other instruments. But that wasn’t what God wanted. He wanted David to study the “right” way, His way of properly bringing the Ark back to Jerusalem with specific instructions that date back to the times of Moses.
Or look at Saul; the Lord specifically instructed Saul to destroy everything in the Lord of Amalek. Saul, however, only destroyed what he thought were “vile and refuse”, sparing and bringing the richest of the lambs and the fattest of the oxens (1 Samuel 15: 1-22). Saul’s excuse was that these animals would be used as sacrifices for God, which prompted Samuel’s to say the famous “to obey is better than sacrifice.” (1 Samuel 15:22)
We may love God with all our hearts and soul, but keep in mind that God wants us to obey His will, not for us to decide what’s best for Him. Sometimes, our best intentions aren’t enough. We must first seek what He wants from us and then give our all.
