The Children of Israel Seeing the promise land, but not entering it, is parallel to Israel seeing the promise of Jesus and Salvation, but not being able to receive it due to lack of faith. It took faith to go into the promise land and it takes faith to be saved. Israel laid eyes on the promise land , but some got discouraged and did not believe that they could enter into it, so they never did. Israel then later down the line saw Jesus , but some did not believe He was who He said He was and did not enter into salvation because they did not believe. Those apart of Israel that believed God were allowed to claim the promise land , and they entered in and received the promises that God promised. Those that saw Jesus and even those who didn't see him yet still believed, received salvation and the kingdom that was promised. It is so important that we believe God when He tells us things and when He makes promises because it will determine whether or not we will access it the way God intended. Believe the promises, believe the instructions, believe you are who God says you are and believe you are capable of what He says you are capable of. Walk in it (faith) and you will see His marvelous works.
Matthew 9:27-31
"As Jesus went on from there, two blind men followed him, calling out, “Have mercy on us, Son of David!” When he had gone indoors, the blind men came to him, and he asked them, “Do you believe that I am able to do this?” “Yes, Lord,” they replied. Then he touched their eyes and said, “According to your faith let it be done to you”; and their sight was restored. Jesus warned them sternly, “See that no one knows about this.” But they went out and spread the news about him all over that region."
