We as professing Christians need to let the influence of heavenly Truth guide us into rightly dividing the Word of Truth, and avoid leaning to the wise and prudent for guidance, since Christ said these things (ie: His revealed Truth) is hid from them, and revealed to babes.
God so loved the world (ie:mankind); He is referring to all, everyone, when He says many; but the reality is that only few will make it, which Christ indicates to us in His sermon, saying, “Not everyone that saith unto me, Lord, Lord, shall enter into the kingdom of heaven”; again, “Many will say to me in that day..”.
Many will follow the way to destruction, and only few will follow the way to life.
Everything that Christ tells us is one way or the other: We must either be a good tree with good fruit, or else we must be a corrupt tree with corrupt fruit; or if we forgive others, then God will forgive us, but if we do not forgive, then neither will He forgive us; or when we hear the things that He tells us to do, then either we do them, or we do them not.
Everything Christ teaches us is exactly agreeable with the law of equity. So when He tells us many are called, but few are chosen, it is the many´s own fault, because they chose which side they wanted; Christianity is voluntary to for righteousness and against sin, but there be some that suppose that a person can modify righteousness to accommodate sin, and get away with it, that is what that parable is illustrating; because people, including some in the church, suppose that they can get away with their own will, with no consequences.
