But as many as received Him, to them He gave the right to become children of God, to those who believe in His name. John 1:12
The "He" and the "Him" in these verses is Jesus Christ, the Son of God. He came to earth to save His people, but many of His own people rejected Him. For those who "received Him," Jesus gave them inheritance into the kingdom of God. All they had to do was "believe in His name." There was nothing else to do, not even their best religious works would be good enough to earn salvation. The same is true for us today as we have the Word of God to teach us about Jesus. The Gospel of John was written so that we would believe in Him, a simple message that requires simple faith. But is it really that simple?
The short answer is "yes." It is just that simple. All anyone has to do to be saved and inherit eternal life with God in heaven is to believe in His Son Jesus and the work He did on the cross. If it is that easy, then why doesn't everyone believe? Jesus would compare the faith required of us to the faith of a child. He desires for all of us to have childlike faith. Why? Because children just believe. They trust without proof of purchase. They do not carry baggage from years of pain, mistrust and betrayal. They do not know what it means to be skeptical, cynical or illogical. But we do. We get hardened by the world and its imprints on our lives. And, unfortunately, some have been hurt by Christians themselves. Even those of us who are Christians, who believe in Jesus, walk around without any power to change. Where is the victory that overcomes the world? In everyday life, it is not so easy to believe in a God we cannot see or hear or touch. When the world takes our time and attention, we have an even harder time believing beyond what we are dealing with at the moment.
If you feel overwhelmed with life, take a moment and set your eyes on Jesus. Ask Him to help you believe His promise to never leave you nor forsake you (Hebrews 13:5). Ask Him to help you believe that He has a future and a hope for you. (Jeremiah 29:11) Ask Jesus to fill you with His peace that He promised to leave with you (John 14:27). Stop trying to work it all out for yourself. And if you are having trouble believing, ask the Lord to help you even to believe (Mark 9:23-24). We spend so much time on other things; why not spend some of it with the Lord today?
