The apostle Peter was made of flesh and blood, just like the rest of us. Yet he wielded spiritual authority over the devil. He said to the lame man at the temple gate, "In the name of Jesus Christ of Nazareth rise up and walk" (Acts 3:6), and the man was healed. The religious leaders of the day recognized this power in Peter and asked him, "By what power, or by what name, have ye done this?" (4:7).

I believe the Church today is in a full-blown crisis over its lack of spiritual authority. I regularly receive calls from pastors and parents who are panicked about their children. They plead, "I just discovered my child is a drug addict and I don't know what to do."

One of the supreme marks of a mature believer is love for all of lost humankind. Such a Christian shows love equally for Jews and Palestinians, for Bosnians and Serbs, for everyone.

A sure sign of spiritual growth is that you take every problem and crisis immediately to Jesus. You have learned that you have a place to go.

“Be careful for nothing; but in everything by prayer and supplication with thanksgiving let your requests be made known unto God” (Philippians 4:6).

Satan has tripped up many Christians by convincing them they’ve lost something in the Lord. The fact is, it’s a terrible sin to doubt God’s love for you and to misjudge your position in Christ by your feelings. Your day-to-day standing with Jesus has nothing to do with your zeal, tears or intensity. It rests on faith alone.

Conversion experiences are often emotional, because they are new and so incredibly special. The change that occurs in our souls is so sudden, it can be overwhelming. It is marvelous to suddenly be turned from sin and bondage to a whole new life in Christ.

“For we walk by faith, not by sight” (2 Corinthians 5:7).

Every day you do things over and over that become boring and repetitious. For example, every weekday you get up at the same hour, eat the same breakfast and make the same drive to your office. You go to the same restaurant for lunch, stop at the same coffee shop on your way home, and listen to the same radio station during the drive.

You may be totally oblivious to the tremendous maturing process taking place inside you. Paul likens our spiritual growth to the growth of our bodies. He says our souls are nourished in the same way as our physical joints, muscles and fibers. He calls this being “[increased] with the increase of God” (Colossians 2:19).

The apostle Paul assured the Thessalonians that they had learned how to walk pleasing before the Lord. He told them, “Ye have received of us how ye ought to walk and to please God” (1 Thessalonians 4:1). Paul then added this exhortation: “So ye would abound more and more” (4:1).

To abound means to increase. Paul was saying, “You’ve been sitting under sound gospel preaching so now you have a solid foundation beneath you. Therefore, you ought to be increasing in grace in all ways—in your faith, your knowledge, your love.”

The Lord instructed John, “Unto the angel of the church in Sardis write; These things saith he that hath the seven Spirits of God . . . I know thy works, that thou hast a name that thou livest, and art dead” (Revelation 3:1).

Jesus is saying, “You may be a good person, someone who’ll do anything for anybody. You’ve got a good reputation among both the church and the world. You’re known as being truly alive in Christ, blessed of God. But an element of death has crept into your life. Something of the world has defiled you.”
