In coming to Christ we do not "make Jesus Lord" (He is already Lord) or "invite Him into our hearts" (a phrase found nowhere in scripture). Christianity is not a commitment to Christ. It is a complete surrender of ourselves to Him. Not only our "religious life", but our whole being. Our heart, family, resources, job, dreams, desires, relationships, ambitions, goals--everything that makes us who we are--are given over to Christ without reservation. We do this regardless of the consequences, knowing that gaining Christ is worth more than anything this world has to offer.
Prayer for Peace - Personal Peace - It is human nature to worry, become fearful, or desperate when one’s life is in excessive turmoil. But Philippians 4:6-7 says, “Don’t worry about anything; instead, pray about everything. Tell God what you need, and thank him for all he has done. If you do this, you will experience God’s peace, which is far more wonderful than the human mind can understand. His peace will guard your hearts and minds as you live in Christ Jesus.” Some other verses regarding personal peace are:
Live in Peace (Mark 9:50)
Jesus overcomes trials and sorrows (John 16:33)
Peace is a fruit of the Holy Spirit (Galatians 5:22-23)
Christ gives peace and rest to all who come to him in faith (Matthew 11:28-30)
Jesus gives us peace of mind and heart (John 14:27)
Jesus is the Prince of Peace (Isaiah 9:6)
