Jesus speaks in His Sermon on the Mount regarding the character of those in His kingdom. His people are to be those who hunger and thirst for a fully-orbed righteousness. They are to thirst fo the declarative righteousness that is theirs through their union with our perfectly just Christ, as well as to hunger for a genuine, ethical righteousness in our practical living.
As children of God, we have no reason to give our hearts over to anxiety. He knows our need even better than we do. Our heavenly Father will be faithful to provide everything His children need to glorify Him. He will never leave us or forsake us.
Jesus’s kingdom prioritizes those that seek to be last, and Jesus himself is the prime example. His parable of the vineyard workers demonstrates the envious tendencies found in every man’s heart.
At first glance, this text seems to support the idea that if we do good things for people in need, we will go to heaven, but that is far from the truth. Christ does indeed encourage us to manifest righteous behavior and to do good works, but our labors are not what saves us; they are evidences of the fact that Christ has saved us by His work on our behalf. As we are in Christ, we will bear out the fruit of Christ, and one of the most significant fruits of Christianity is our compassion for those in need, particularly our compassion for the fatherless.
