"Love never faileth..." (1 Corinthians 13:8)
The love of Jesus is without peer. Nothing in this world even comes close to its white-hot fervence and purity. It's like precious metal that can be hammered out continuously without losing its strength and staying power. That's how you know that it's really love: if what you feel stays through thick and thin. And the only way to know the true love of Jesus is to know Him. He is love. Three words. Infinite dimensions.
And this is where the idea of tolerance comes in. There are many levels to life. Too many to list here. But know that the love of Jesus shines through all of them. If you come upon a situtation that doesn't mesh with His character or His tenets, know that any judgment that you level at that person or situation should be done in love. If you don't know that it's love— if you don't know that what you're going to say comes from a motive of love (for God and them), pause to think. Pause to reflect on how God would love you in that situation and circumstance. The good news is that, what might look like tolerance for sin and shortcoming on one level, has, actually, the love of God at its root. And if the love of God is at the core of your motive, anything springing from that core will produce the fruit of love. Your smiling silence doesn't mean that you approve of what they're doing, it means that you love them more.
"Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man's device. And the times of this ignorance God winked at; but now commandeth all men every where to repent." (Acts 17:29-30)
Okay, so the first verse of the above passage kinda renders my precious-metal parallel moot. There's nothing (not even platinum?) that compares to God's being—His Personhood. This is why idolatry is such a joke. Because God cannot be contained within a mere representation. So check out the second verse. It says that God allowed idolatry for a season. He "winked" at it. Meaning...He shut one eye? That is what a wink is. And if God is equal parts love and judgment, I would have to say that His depth perception—His tolerance for sin can, now, only go so far. Forgiveness is here for everyone and everything ladies and gentlemen. And if we're not appropriating the abundance of the forgiveness that Jesus died (died) to provide for us, then His tolerance will wear thin.
Yes, we can show tolerance in certain realms of life. And yes, there are times that the Holy Spirit will have you speak up. Just make sure that it's really Him and that you're really walking in love. Anything less will cause the gears to grind—no matter the metal.
Oh, and 'metal' has three homophone siblings: mettle, medal, meddle. So there.
