Many people have been told to believe in Jesus for salvation, but you need to WALK WITH Jesus, to have salvation. Believing in Jesus will not save you if you do not obey and follow Him.
We read in John 1:12"But as many as received Him, to them He gave the right to become children of God, even to those who believe in His name, 13who were born, not of blood nor of the will of the flesh nor of the will of man, but of God." Not all believers are children of God, because not all believers are born again. Not all believers have received Jesus as Lord and Master.
To those who receive Jesus and who receive and obey His words, He gives the POWER to become children of God. Those who believe in Him, repent and are baptized in water, they are born again, those who obey His words as they are also recorded in Matthew, Mark, Luke and John. Jesus baptizes in the Holy Spirit. He baptizes those who obey Him. He gives His Holy Spirit in them, to be with them, to teach and guide them, so that they can follow Him, and walk with Him.
"Those who are being led by the Spirit of God, they are the sons of God," they are children of God. (Romans 8:14).
Many people are believers. They have a church, and a Bible, and a pastor, and they believe they have salvation, but they do not have Jesus. They never accepted Him, never obeyed Him, were never born again, never knew Him, never followed Him, never walked with Him. They believe in Jesus like they believe in father Christmas and ghosts, and halloween. To them Jesus is a story, a myth, a fable.
Many just walk with their Bible, in their head and under their arm, or nowadays, in their smart phone, but they don't have Jesus. They do not know Him. They are lost and doomed.
You need to accept Jesus, obey Him, be born again, filled with the Holy Spirit, and follow the guidance of the Holy Spirit to be able to walk with Jesus.
Do you have Jesus? Have you been born again? Do you have His Holy Spirit in you? Do you walk with Him, follow Him, every day? Are you a child of God or just a believer?
May Jesus bless you.
