When we become believers, the Most High God adopts us as His children (Galatians 4: 5-7). Since Jesus is the begotten Son of the Most High God, we become his little sisters and brothers. What are some things that a big brother does for his younger siblings? He protects, helps care for them, watches them, speaks up for them, sometimes fights for them, scolds them, sets an example for them, teaches them, gets them out of trouble, loves them, etc. Jesus does all of this for us and more.
Jesus also shares His inheritance with us. “The Spirit itself beareth witness with our spirit, that we are the children of God: 17 And if children, then heirs; heirs of God, and joint-heirs with Christ…” (Romans 8:16-17 KJV). Jesus is not a selfish big brother. He wants to share with us. In fact, He instructs us to use His name to get what we need. “And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. 14 If ye shall ask any thing in my name, I will do it” (John 14: 13-14 KJV).
Jesus is also not a jealous or envious Big Brother. Jesus does not mind if younger siblings achieve more than He achieved while He walked the Earth. In fact, Jesus is counting on us to do more. “I assure you and most solemnly say to you, anyone who believes in Me [as Savior] will also do the things that I do; and he will do even greater things than these [in extent and outreach], because I am going to the Father” (John 14:12 AMP).
