Mujahideen: solid, liquid, and gas does not only refer to H2O. It refers to matter. There are other examples anyway. The universe is one and it consists of time, matter, and space. Those 3 are not the same yet they are one in the uniniverse. Also, there is a trinity within that. As mentioned, Matter can be: solid, liquid, gas. Time can be: past, present, future. Space can be: length, width, height. There are so many examples.
John 10:17-18>Therefore doth my Father love me, because I lay down my life, that I might take it again. No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father.
Christ WILLINGLY gave His life. No one took it from Him. That's just the way the Father is. He will not allow imperfect man to enter Heaven by their own righteousness because God is too perfect for that. Rather, we enter Heaven by a foreign righteousness through Christ. We are not saved by our good works. But we have to do good works in order to prove our faith. Another thing Muslims fail to realize is, not only did Christ die, He resurrected with power. If He died and will no longer exist ever again, then you will have a point. But He brought Himself back up again.
