"17 Therefore, if anyone is in Christ, the new creation has come:[a] The old has gone, the new is here! 18 All this is from God, who reconciled us to himself through Christ and gave us the ministry of reconciliation: 19 that God was reconciling the world to himself in Christ, not counting people’s sins against them. And he has committed to us the message of reconciliation. 20 We are therefore Christ’s ambassadors, as though God were making his appeal through us. We implore you on Christ’s behalf: Be reconciled to God. 21 God made him who had no sin to be sin[b]for us, so that in him we might become the righteousness of God." (2 Corinthians 5:17-21)
You are an ambassador of Christ. You carry his name. You show his love to the world. When you are able to walk through trials and tribulations in life by trusting in Christ's power, those around you will notice.
When life hits you in the face, and you want to give in, keep walking! Jesus is with you through every trial. When you are hit by life, and others see you continuing to walk, they will take notice.
It's hard to walk through life at times. But as trials come, and you continue to trust in Christ, others will be pointed to Christ. You can show Christ to the world by sharing the gospel, or showing love, or being bold in your faith.
You can also point people to Christ by trusting in him in the midst of your trials, and continuing to walk. There is power in seeing someone walk through a trial because they have Christ on their side.
