1. An explanation of faithfulness
Now faith is being sure of what we hope for and certain of what we do not see. Hebrews 11:1
But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control. Against such things there is no law. Galatians 5:22-23
For the LORD is good and his love endures forever; his faithfulness continues through all generations. Psalm 100:5
His divine power has given us everything we need for life and godliness through our knowledge of him who called us by his own glory and goodness. Through these he has given us his very great and precious promises, so that through them you may participate in the divine nature and escape the corruption in the world caused by evil desires. For this very reason, make every effort to add to your faith goodness; and to goodness, knowledge; and to knowledge, self-control; and to self-control, perseverance; and to perseverance, godliness; and to godliness, brotherly kindness; and to brotherly kindness, love. 2 Peter 1:3-7
But when he asks, he must believe and not doubt, because he who doubts is like a wave of the sea, blown and tossed by the wind. That man should not think he will receive anything from the Lord; he is a double-minded man, unstable in all he does. James 1:6-8
2. Examples of faithfulness
God, who has called you into fellowship with his Son Jesus Christ our Lord, is faithful. 1 Corinthians 1:9
No temptation has seized you except what is common to man. And God is faithful; he will not let you be tempted beyond what you can bear. But when you are tempted, he will also provide a way out so that you can stand up under it. 1 Corinthians 10:13
if we are faithless, he will remain faithful, for he cannot disown himself. 2 Timothy 2:13
Therefore, holy brothers, who share in the heavenly calling, fix your thoughts on Jesus, the apostle and high priest whom we confess. He was faithful to the one who appointed him, just as Moses was faithful in all God’s house. Hebrews 3:1-2
From that time on Jesus began to explain to his disciples that he must go to Jerusalem and suffer many things at the hands of the elders, chief priests and teachers of the law, and that he must be killed and on the third day be raised to life. Matthew 16:21
3. Applications of faithfulness

So then, men ought to regard us as servants of Christ and as those entrusted with the secret things of God. Now it is required that those who have been given a trust must prove faithful. 1 Corinthians 4:1-2
B. Faithful in marriage
No widow may be put on the list of widows unless she is over sixty, has been faithful to her husband, and is well known for her good deeds, such as bringing up children, showing hospitality, washing the feet of the saints, helping those in trouble and devoting herself to all kinds of good deeds. 1 Timothy 5:9-10
C. Faithful in prayer
Never be lacking in zeal, but keep your spiritual fervor, serving the Lord. Be joyful in hope, patient in affliction, faithful in prayer. Share with God’s people who are in need. Practice hospitality. Romans 12:11-13

You learned it from Epaphras, our dear fellow servant, who is a faithful minister of Christ on our behalf, and who also told us of your love in the Spirit. Colosians 1:7-8

Do not be afraid of what you are about to suffer. I tell you, the devil will put some of you in prison to test you, and you will suffer persecution for ten days. Be faithful, even to the point of death, and I will give you the crown of life. Revelation 2:10
If anyone is to go into captivity, into captivity he will go. If anyone is to be killed with the sword, with the sword he will be killed. This calls for patient endurance and faithfulness on the part of the saints. Revelation 13:10
