Titus 1:15-16 Everything is pure to those whose hearts are pure. But nothing is pure to those who are corrupt and unbelieving, because their minds and consciences are defiled. Such people claim they know God, but they deny him by the way they live. They are despicable and disobedient, worthless for doing anything good.
Titus 2:1b-7,11 Promote the kind of living that reflects right teaching. Teach the older men to exercise self-control, to be worthy of respect, and to live wisely. They must have strong faith and be filled with love and patience. Similarly, teach the older women to live in a way that is appropriate for someone serving the Lord. They must not go around speaking evil of others and must not be heavy drinkers. Instead, they should teach others what is good. These older women must train the younger women to love their husbands and their children, to live wisely and be pure, to take care of their homes, to do good, and to be submissive to their husbands. Then they will not bring shame on the word of God. In the same way, encourage the young men to live wisely in all they do. And you yourself must be an example to them by doing good deeds of every kind. Let everything you do reflect the integrity and seriousness of your teaching. For the grace of God has been revealed, bringing salvation to all people.
Hebrews 4:1-3a,7e,f Therefore, since a promise remains of entering His rest, let us fear lest any of you come short of it. For indeed the gospel was preached to us as well as to them; but the word which they heard did not profit them, not being mixed with faith in those who heard it. We who have believed do enter that rest… it has been said: “Today, if you will hear His voice, Do not harden your hearts.”
Hebrews 6:11-17 Our great desire is that you will keep right on loving others as long as life lasts, in order to make certain that what you hope for will come true. Then you will not become spiritually dull and indifferent. Instead, you will follow the example of those who are going to inherit God’s promises because of their faith and patience. For example, there was God’s promise to Abraham. Since there was no one greater to swear by, God took an oath in his own name, saying: “I will certainly bless you richly, and I will multiply your descendants into countless millions.” Then Abraham waited patiently, and he received what God had promised. When people take an oath, they call on someone greater than themselves to hold them to it. And without any question that oath is binding. God also bound himself with an oath, so that those who received the promise could be perfectly sure that he would never change his mind.
