They seem like contradictions to you (or maybe not you but others) because you (or they) are not putting them in context. To me, they are in complete harmony with all the rest of scripture...
Listen, you seem to not even understand the question I've asked you, yet you want to argue complex issue as predestination. I asked you precise question about seeming contradictions because that needs to be clear, I believe, to the one who wants to have good understanding of any issue in the Bible.
The question was "Why are there seeming contradictions in the Bible on many different issues (not just this one issue)"? Do you get the question - why, not how or do you presumably have or don't have problems with this or that verse.
Let me help you a bit, because I am asking the question for the third time.
In Matthew 28:19 Jesus commands: "Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit." Yet in Acts none of the recorded baptisms were done in the name of the Father and of the Son and of the Holy Spirit, while mostly in the name of Jesus alone.
James writes: "Show me your faith without deeds, and I will show you my faith by my deeds. You believe that there is one God. Good! Even the demons believe that—and shudder. You foolish person, do you want evidence that faith without deeds is useless?" Yet other verses point that one is saved thorugh faith alone. Jesus even says that works themselves are faith, not physical works - when people ask Jesus "What must we do to do the works God requires?" (John 6:28) Jesus answers: "The work of God is this: to believe in the one he has sent."
In John 6 Jesus says: "Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day. For my flesh is real food and my blood is real drink. Whoever eats my flesh and drinks my blood remains in me, and I in them." This command for communion (and other verses I didn't quote here) suggests literal communion is necessary for salvation. Yet there are other verses that don't put communion as condition for salvation. Similar contradiction surrounds water baptism.
In John's first epistle, third chapter, John writes: "You know that he appeared so that he might take away our sins. And in him is no sin. No one who lives in him keeps on sinning. No one who continues to sin has either seen him or known him." So it literally says that "no one who continues to sin has either seen Jesus or known Jesus." Yet in first chapter of the same epistle John writes: "If we claim to be without sin, we deceive ourselves and the truth is not in us." And John, by the way, is writing to believers. Also, we know that nobody is sinless even if he or she is born again.
And on and on. There are seeming contradictions for most issues in the Bible. Verses that literally oppose one another on the same issue. At this point, I am not even sure you understand the gravity of that fact. But let's say you do get that there are seeming contradictions, and you are actually humbled by it. My question is: "Why are there seeming contradictions, verses that directly oppose one another on the same issue, for many issues in the Bible?" Why?
