How do you think you'd respond if God asked you to hang on a cross?
We think Abraham being asked to sacrifice his son was the ultimate test, but think about Jesus...asked to give up his own life. Which is easier? Give up your life or the life of someone else? And don't say, "He was God." Jesus was not God...if he was God, why was he asking God to let the cup pass? What? Like the movie, "Oh God" with George Burns as God, when asked to swear on the Bible, "So help me, me?"
No, Jesus is not God...he is the first-born Son of God. Important? Yes. God? No. God said, there is only one God (Deuteronomy 6:4) so how can Jesus be God and the Holy Spirit be God? I explain the Trinity in another post...suffice it say, Jesus sweat blood knowing what was going to happen to him. So how did he endure it?
Jesus knew, without a doubt, God was real...so while his "human" side was agonizing over his pending death on the cross, the Spirit of God was assuring him a better life awaited him. Victory over death, is the final victory. (1 Corinthians 15:5)
The trials and tribulations we face are nothing compared to what our Lord experienced. We are pushed to the limit, but God never gives us more than we can handle and always makes a way out. Nevertheless, when you're being pushed to the limit remember what God said when I cried, "Why have you forsaken me?" His reply, "I didn't ask you to hang on a cross." It will put things in perspective for you.
But, until you know, without a doubt, God is real...nothing else matters.
