Spending time with God can feel like a burden, but as Christians, we are called to abide in Jesus. John 15, says, Jesus is the true vine. So just like a vine has branches, Jesus is the vine and we are the branches that are attached to Him. As we spend time getting to know him, our lives are filled with more joy and Christlike fruit. Spending time with Jesus comes more naturally because we love Him and want to abide in him as his true followers.
I am the vine; you are the branches. Whoever abides in me and I in him, he it is that bears much fruit, for apart from me you can do nothing. If anyone does not abide in me he is thrown away like a branch and withers; and the branches are gathered, thrown into the fire, and burned.
