Among all the identities that we have, the first and most important one is that we are God's children. Have you ever felt that God has given up on you because, instead of walking confidently in faith, we sometimes stumble and fall? Have you ever feared that there is a limit to God's patience for your failure and your lack of self-discipline when you are fighting your temptations? The primary truth is God's love and acceptance is unconditional. When our faith is strong, God loves us; when our faith is weak, God loves us; when we succeed, God cheers for us; when we fail, God comforts us. God's love never changes, and it never fails. 
Unbelievers cannot fully comprehend us Christians because they fail to fully comprehend God. Those in the world associate us with fanatics or enthusiasts, as foolish in abandoning things they enjoy, as renouncing certain happiness for something uncertain. When Jesus came into the world, the world didn't recognize Him as the Son of God. When we feel rejected by the world, we experience only what Jesus Christ has experienced. As God's children, we can be sure that He will make us just like Jesus.

Dear Heavenly Father, I am so blessed that You call me Your child. Thank you for sending Your son, Jesus Christ, into the world so we can see You and know who You are. Your love for me is beyond measure and never stops. Even though I may not always fit in the world, I know You are and will always be with me. Father, teach me how to love others the way You love them so they can recognize You through me. 
In Jesus's name I pray. Amen.
