When we do not think like God, we are not in His image. We cannot say as Jesus did, "He who has seen Me has seen the Father" (John 14:9). God, in His wisdom, has willed that we grow in His image through exercising faith in what He says, buttressed by what He reveals of Himself in His creation.
The fundamental difference between the person of faith and the unbeliever is revealed by the way they judge things. The unbeliever, of the world, judges things by worldly standards, by his senses, and by time. The person learning to think like God brings God into everything, viewing things from His perspective, by His values. He ascertains how the activity, event, or thing looks in terms of eternity. He seriously meditates on God's sovereignty over all things. At times, doing this puts the screws to his trust because the Bible says that God's judgments are "unsearchable . . . and his ways past finding out" (Romans 11:33). Faith holds a person steady.
Because we often do not think like Him, and because we do not have His perfect perspective, we often do not exactly know what God is doing. Only in hindsight do we understand what is occurring in our personal life, to the church, or in the world in the outworking of prophecy. So we must trust Him, and in the meantime weigh what is happening and its possible outcome.

The Sovereignty of God: Introduction
This paragraph presents an overall and continuous solution to this weakness in the lives of the converted. First, notice that this paragraph is in the form of a command. It is not a mere suggestion but a direct charge from our Creator. As the reference to David indicates, it is addressed to His people, so His audience already knows Him to some degree. The word "return" (verse 7) confirms this, indicating that He and they already have a relationship, but those He is speaking to have lost some resolve and drifting apart has occurred.
The mention of David appears in verses 3-4. When this was written, David had been dead for about 250 years, so this inclusion inserts some symbolism and moves the time-setting, making it a prophecy that fits it into the end time as well as Isaiah's lifetime. David is a type of Jesus Christ in His office as King, which further confirms that God is commanding this of those who already know and have a relationship with Him. Not only have these people drifted away, but they are also not making the effort to "seek" Him to strengthen the relationship.
The responsibility of those who have made the covenant with Him to seek Him is thus not that of striving to find Him in order to establish a relationship as a relationship already exists. Rather, it is seeking Him in order to be like Him and become more fully intimate with His will.
Verses 1-3 remind us that our relationship with Him is not without cost. This paragraph begins with an urgent command: "Come!" The sense is that paying the cost of seeking is obligatory if the relationship is to continue.
We need to understand our position here. God not only loves us, but He also greatly desires us to be in His Kingdom. At the same time, He wants us to show voluntarily that we desire the relationship. In addition, to reinforce our obligation, we must grasp and fully accept that He has every legal right to command us to do this.
In Isaiah 55:1-3, our part in this relationship is clearly not costly in terms of money, but it is in terms of our lives and how we spend them. Our lives must be lived by faith in the One who redeemed us. Paul describes the Christian life as a living sacrifice (Romans 12:1).
