Since Jesus Christ committed no sin, He can pay the penalty for our sins. No other person can make this claim. The ministry of Jesus Christ lasted approximately 3 years. He performed many miracles to demonstrate His power and authority as well as His love for people. Most were physical healings.
Some examples are below.
Without the resurrection of Jesus Christ from the dead, the Christian faith would be empty and meaningless just like all other religions and philosophies. Read Mathew 26 - 28. Then, you will understand why Easter is a time of great celebration for every Christian. Since we do not know the hour when Jesus Christ will return to this earth or when we may meet our untimely death, making a decision about Him must be the most important priority. Therefore keep watch, because you do not know on what day your Lord will come.
