No where in Gods word does it say that life will be easy. In fact it says just the opposite. If we live Godly we will suffer persecution. Also there will be times when God prunes us so that we may bring forth more and better fruit. This pruning process can be painful as God works to strip away things in our lives that hold us back and teach us things that will make us more Christlike. No believer gets a free pass or is exempt from hard times. No amount of obedience will keep us from from troubles if it is Gods will to allow them for some reason.
But what God does is call us to persevere, just as He did the church at Philidelphia. God said that the Church had a "little strength". And maybe thats how you feel, that you only have a little strength. God knows that about you just as He knew it about the Church at Philidelphia, and He wants to give you His strength and help you persevere.
Is perseverance easy ? Of course not. We can only do by His grace and His empowerment. His Holy Spirit dwells within us us to supernatuarlly help us to endure and persevere. He calls us to persevere when we are in less than perfect circumstances, but He doesnt call us to do it on our own, He desires to help us. But we must rely on Him, confessing humbly that we cant do it on our own.
Maybe you are in the midst of a trying time right now. And maybe God has chosen to allow this time to stay for now. Friend hang on to God, depend on Him and trust him to help you to persevere. You will find that what God chooses not to change, He gives us the grace to not only endure, but to thrive and be blessed by Him in the midst of it. Just like Joseph who God blessed amazingly even while he was a slave and in prison. we serve that same omnipotent God. He will help you to persevere. Trust Him and lean on Him.
