Be transformed through the gospel of Christ (1 Corinthians 15:1-4). The word of the gospel is the instrument for your transformation. The Holy Spirit is the agent who transforms you (1 Thessalonians 1:5). Knowing Jesus as Lord is the result (Romans 10:9; 1 Corinthians 12:3).
Be transformed through the power of the Holy Spirit (John 3:8). The Holy Spirit works through the gospel of Christ (1 Thessalonians 1:5). No one could ever be transformed without the Spirit of God working in us. You are transformed by the Spirit of God changing your heart.
Be transformed with a change of mind, will and emotions. You are transformed from within. Before we are transformed in Christ, we are conformed to this present evil world. Transformation is a change in your heart through the Holy Spirit. God transforms you as a new creation in Christ (2 Corinthians 5:17).
"And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God" (Romans 12:2).
Be transformed with a mind that understands spiritual things (1 Corinthians 2:14). He enables you to see and believe the truth of Jesus Christ. The Holy Spirit transforms your mind to understand the truth of God in the Bible. We are transformed by the grace of God to the glory of God.
