I’m quite in agreement with you that in this life we will have troubles, just as Jesus said (John 16:33). I believe that taking up our own cross ties in with what Paul said about putting to death the deeds of the body by the Spirit. (AMP says "the deeds prompted by the body." Of course, this is referring to sinful deeds.)
Romans 8:12-14--So then, brothers, we are not obligated to the flesh to live according to the flesh, for if you live according to the flesh, you are going to die. But if by the Spirit you put to death the deeds of the body, you will live. All those led by God’s Spirit are God’s sons.
This is also a good passage:
1 Peter 2:21-25--For you have been called for this purpose, since Christ also suffered for you, leaving you an example for you to follow in His steps, WHO COMMITTED NO SIN, NOR WAS ANY DECEIT FOUND IN HIS MOUTH; and while being reviled, He did not revile in return; while suffering, He uttered no threats, but kept entrusting Himself to Him who judges righteously; and He Himself bore our sins in His body on the cross, so that we might die to sin and live to righteousness; for by His wounds you were healed. For you were continually straying like sheep, but now you have returned to the Shepherd and Guardian of your souls.
