The reason why believers stray and stumble is because they do not follow Jesus Christ. Most of them never started following Jesus, they do not get their guidance from Him but from other people and from their own interpretation of the Bible.
The words of Jesus are the words of eternal life. Those words are recorded in the gospels, Matthew, Mark, Luke and John. If we obey those words then we will have eternal life. If we do not understand or if we are not sure we have to PRAY and ASK Jesus and the Holy Spirit will explain the words of Jesus to us. He will give us INSIGHT, WISDOM, He will guide us into all truth. But if we keep on asking other people, reading little books, listening to others, seeking our wisdom from others then we are not following Jesus and that is when people fall into the ditch. A true man of God will send you to Jesus, tell you to go and pray and wait on the Lord and THE LORD WILL SPEAK TO YOU.
The apostle James wrote in James 1:5 “If any man needs wisdom let him ask of God who gives to all men freely.” If you need understanding, ASK JESUS. If you need guidance and insight, PRAY and ASK JESUS and HE WILL GIVE YOU UNDERSTANDING! But you need to ASK HIM, you need to FOLLOW HIM, not people, not the pastor, not other people. Go on your knees and cry out to the living God, WAIT on Him and He will guide you.
If you are not following Jesus you are following strangers and you will PERISH. Jesus Christ ALONE is the WAY the TRUTH and the LIFE. Follow HIM. Who do you go to? To Jesus or to other people? Who are you following? Are you REALLY following Jesus Christ?
May Jesus bless you.
