Have you ever felt that you could get no peace. You were troubled about something, and you could not be at rest about a decision or a situation in your life. The worry gnawed at your heart, and you may have lost your joy. If we are troubled about something we are not allowing the peace of God to affect us.
When Jesus left this earth, he gave us the Holy Spirit. He makes this comment, "Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid." John 14:27 Jesus said that He gave us peace. This wasn’t any ordinary earthly peace of mind. Notice Jesus’ comment, "Not as the world giveth." If we try to gain peace of mind from this world system, or our own reasoning we will ultimately fail. This world has nothing to offer us that can give us peace. Only Christ can give peace.
So I would like to encourage you, focus on Christ. Rest in the peace that God has given you. Jesus said in John, "Peace I leave with you." You already have it. So put God into your remembrance. Remember His greatness. Pray to God and commune with Him. If you associate with God and rest in His promises, you will receive the true peace that your soul longs for.
Isaiah 26:3 says, "Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee."
