Isaiah 40:29 He giveth power to the faint; And to them that have no might he increaseth strength.
He is the answer to all of our needs. If you are tired in your spiritual life and walk know that He gives power to the faint. He will give you strength to go on. Life can take its toll. Getting old isn’t the funnest thing in the world but you are not alone.
Well, you are alone if you are not born again, saved. If you have never come to Christ and received the free gift of salvation then you are there alone drowning with no help in you. But the help is right there in front of you. He loves you. He died for you. He has already paid your sin debt. He offers you a free gift. He just asks you to believe Him.
If you are born again then you need to know that it is time to quit trying so hard. Quit living in yourself and your ability. Learn to trust God and what He has done and is doing. He will give you the power to go on. He will give you strength. He wants you to enjoy an abundant life in Him. It is all done. All paid for. It is yours for the trusting.
