Trusting Jesus for salvation, and believing and taking and trusting Him at His Word, go hand in hand. Ask yourself why Jesus would give us any untruths in His own Word. We either believe it all, or not at all. The more you read God's Word, you will see there are no contradictions. God is no liar and he does not contradict Hisself. The so-called "contradictions" that people bring up, are because they have not read scripture in context nor the history of it, what was going on at the time, and all these things make a big difference, including who was being spoken to. There are no contradictions in God's Word. Only what people make up in their own minds, because they have not read the Word nor understand it. If you can't believe all of God's Word, then how can you take him seriously about His standard for salvation? God is incapable of lying. He does not make mistakes nor errors. This is why God said to study His Word diligently, so we are not confused or have to guess. Satan is the author of confusion. There's no speculation in the Word of God. He said what He meant and meant what He said. This is why Bible study is so important. It is God's literal road map for mankind in life. We just can't pick out parts we're going to believe, or not. It's either true or it isn't. Satan is a liar. God did not entrust His Word to just anyone, but the Bible says to holy men of old, were taught and told what to write as the Holy Spirit led them.
You can look to outside religions all you want, but when Jesus said He is the Way, the Truth, and the Life, that's what he meant. You can stray from God and His Word, but Jesus said there's only one path that leads to salvation and eternal life in heaven. Be careful who you listen to because those who are not believers, will lead you away from Christ and His Word. We either believe God or we don't. You have to make up your mind. All you will find in all religions, which are nothing but man-made philosophies, are what God teaches AGAINST in His Word.... worshiping idols and praying to statues and believing that the way to heaven is by doing good deeds. Man did not get the privilege of setting the standard for salvation FOR God. Sinful man does not know the way. Who better knows the way of salvation and who set the standard for salvation, but God? Tell me what "religion" died on the cross for your sins. None of them and none of their gods. But Jesus did. Living for Jesus and salvation, have nothing to do with denominations. It is trusting in the Living God, Jesus, that God approved and appointed to be our Savior to the world.
